Printing system, printing device, and startup control method for printing device

Abstract

This invention provides a printing system, a printing apparatus, and a method for controlling the start-up of the printing apparatus, which can suppress operator waiting time and reduce the lifespan of consumables. The printing system (100A) includes: a first printer (1A) that, upon receiving a start instruction, performs an initial action to transition to a printable state; and a second printer (1B) that, upon receiving a start instruction, performs an initial action to transition to a printable state. When the second printer is designated as a follower printer (NX) to start after the first printer, a start instruction processing is performed to output a start instruction to the second printer. In this start instruction processing, starting from the moment the first printer receives the start instruction, and at a second start time calculated based on a first initial action time (TP1), a first maintenance time (TM1), and a second initial action time (TP2), a start instruction is output to the second printer.

Description

Technical Field

[0001] This invention relates to a printing system, a printing apparatus, and a method for controlling the start-up of the printing apparatus. Background Technology

[0002] A printing system is known to have multiple printing devices that are connected in a communicable manner.

[0003] For example, Patent Document 1 describes a printing system that is controlled so that maintenance time does not overlap among multiple printing devices.

[0004] Patent Document 1: Japanese Patent Application Publication No. 2017-19181

[0005] However, Patent Document 1 does not describe the maintenance operations performed by the user when starting the printing device (e.g., paper setting, nozzle check, etc.).

[0006] For example, when a user starts multiple printing devices sequentially, waiting time occurs, reducing the user's workability. Additionally, starting multiple printing devices simultaneously generates unnecessary power consumption, reducing the lifespan of consumables. Summary of the Invention

[0007] Therefore, the object of the present invention is to activate multiple printing devices at appropriate times.

[0008] One approach to solving the aforementioned problem involves a printing system comprising: a first printing device that, upon receiving a start instruction, performs an initial action to transition to a printable state; and a second printing device that, upon receiving a start instruction, performs an initial action to transition to a printable state, wherein, when the second printing device is designated as a follower printing device that starts after the first printing device, a start instruction processing is performed to output the start instruction to the second printing device, wherein, starting from the moment the first printing device receives the start instruction, the start instruction is output to the second printing device at a second start time calculated based on a first initial action time required for the initial action of the first printing device, a first maintenance time required for a maintenance operation performed after the first printing device performs the initial action, and a second initial action time required for the initial action of the second printing device.

[0009] Another solution to the aforementioned problem involves a printing apparatus that, upon receiving a start instruction, performs an initial action and transitions to a printable state. The printing apparatus includes: a communication unit communicatively connected to a second printing apparatus that, upon receiving a start instruction, performs an initial action and transitions to a printable state; a start instruction receiving unit that receives the start instruction; a designation receiving unit that receives designations of a follower printing apparatus to be started after the first printing apparatus; a timing unit that times the elapsed time since receiving the start instruction; and a start control unit that, when the second printing apparatus is designated as the follower printing apparatus, performs a start instruction processing that outputs the start instruction to the second printing apparatus. In this start instruction processing, the start control unit, starting from the moment the printing apparatus receives the start instruction, outputs the start instruction to the second printing apparatus at a second start time calculated based on a first initial action time required for the initial action of the printing apparatus, a maintenance time required for maintenance operations performed after the initial action of the printing apparatus, and a second initial action time required for the initial action of the second printing apparatus.

[0010] Another approach to solving the aforementioned problem involves a printing device startup method that enables the startup of a first printing device and a second printing device. The first printing device, upon receiving a startup instruction, performs an initial action and transitions to a printable state. The second printing device, upon receiving a startup instruction, also performs an initial action and transitions to a printable state. When the second printing device is designated as a follower printing device that starts after the first printing device, a startup instruction processing is performed that outputs the startup instruction to the second printing device. In this startup instruction processing, starting from the moment the first printing device receives the startup instruction, and based on a second startup time calculated according to a first initial action time required for the initial action of the first printing device, a first maintenance time required for maintenance operations performed after the initial action of the first printing device, and a second initial action time required for the initial action of the second printing device, the startup instruction is output to the second printing device.

Detailed Implementation

[0024] Hereinafter, this embodiment will be described with reference to the accompanying drawings. The printing system 100 according to this embodiment includes the following components: Figures 1 to 6 The printing system 100A described in the first embodiment, and the reference... Figures 7 to 9 The printing system 100B according to the second embodiment described herein.

[0025] First Implementation Method

[0026] First, the printing system 100A according to the first embodiment will be described.

[0027] Figure 1 This is a diagram illustrating an example of the structure of the printing system 100A according to the first embodiment.

[0028] The printing system 100A includes printer 1. Printer 1 includes a first printer 1A, a second printer 1B, and a third printer 1C.

[0029] The first printer 1A, the second printer 1B, and the third printer 1C are connected to each other via a network NW in a manner that allows them to communicate with each other.

[0030] Network NW is, for example, LAN (Local Area Network). Network NW can also be WAN (Wide Area Network) or the Internet.

[0031] Printer 1 corresponds to an example of a "printing device".

[0032] The first printer 1A corresponds to an example of a "first printing device". The second printer 1B corresponds to an example of a "second printing device". The third printer 1C corresponds to an example of a "third printing device".

[0033] It should be noted that, without distinguishing between the first printer 1A, the second printer 1B, and the third printer 1C, in the following description, the first printer 1A, the second printer 1B, and the third printer 1C are sometimes referred to as printer 1.

[0034] Next, printer 1 will be described. Since the first printer 1A, the second printer 1B, and the third printer 1C have substantially the same structure, the structure of the first printer 1A will be described, while the descriptions of the second printer 1B and the third printer 1C will be omitted.

[0035] The first printer 1A is an apparatus for printing text, images, etc., on printing media such as paper. In this embodiment, the first printer 1A is, for example, a printer used in a printing company that performs printing on relatively large printing media. The first printer 1A is communicatively connected to a computer (not shown) and performs printing jobs based on printing data received from the computer.

[0036] like Figure 1 As shown, the first printer 1A includes a printer control unit 11, a printer communication unit 12, a printer storage unit 13, a printer input unit 14, a printer display unit 15, a printing unit 16, an ink supply unit 17, and a printing media container unit 18.

[0037] The printer control unit 11 includes a processor 11A such as a CPU (Central Processing Unit), a memory 11B such as ROM (Read Only Memory) and RAM (Random Access Memory), an ASIC (Application Specific Integrated Circuit), and signal processing circuits, which control various parts of the first printer 1A. The memory 11B stores the control program.

[0038] Memory 11B corresponds to an example of a "storage unit".

[0039] The printer control unit 11 performs processing through the cooperation of hardware and software. For example, the processor 11A reads the control program stored in the memory 11B to perform processing, or it performs processing through the functions installed in the ASIC, or it performs processing through signal processing circuitry.

[0040] The printer control unit 11 has a start instruction receiving unit 111, a designation receiving unit 112, an operator receiving unit 113, a timing unit 114, a start control unit 115, a start sequence storage unit 116, and a proficiency storage unit 117 as functional blocks.

[0041] These function blocks are used for convenience to represent the functions implemented by the processor 11A through the execution of control programs, and do not represent specific application software or hardware. These function blocks will be described later.

[0042] Under the control of the printer control unit 11, the printer communication unit 12 communicates with other printers 1, namely the second printer 1B and the third printer 1C, according to the prescribed communication standards.

[0043] The printer communication unit 12 corresponds to an example of the "communication unit".

[0044] The printer storage unit 13 is equipped with non-volatile memory such as HDD (Hard Disk Drive), EEPROM (Electrically Erasable Programmable Read-Only Memory), and SSD (Solid State Drive) to store various data in a rewritable manner.

[0045] The printer input unit 14 includes input units such as operation switches and a touch panel provided on the first printer 1A. It detects operations performed on the user's input units and outputs a detection signal corresponding to the operation to the printer control unit 11. Based on the input from the printer input unit 14, the printer control unit 11 performs processing corresponding to the user's operation.

[0046] The printer display unit 15 includes multiple LEDs (Light Emitting Diodes), a display panel, etc. Under the control of the printer control unit 11, it performs tasks such as turning the LEDs on, off, and flashing in a prescribed manner, and displaying information to the display panel.

[0047] Under the control of the printer control unit 11, the printing unit 16 prints text, images, etc. on the printing medium using ink. The printing unit 16 includes, for example, a print head 161, a carriage 162, a scanning motor 163, and a transport motor 164 as printing-related structures.

[0048] The printhead 161 is an inkjet printer that ejects ink supplied by the ink supply unit 17 onto the printing medium. The carriage 162 carries the printhead 161 and scans in a direction intersecting the transport direction of the printing medium. The scanning motor 163 causes the carriage 162 to scan. The transport motor 164 transports the printing medium in the transport direction.

[0049] The ink supply unit 17 contains an ink reservoir and supplies ink from the ink reservoir to the print head 161 of the print unit 16. The ink supplied by the ink supply unit 17 is, for example, various colors of ink such as cyan (C), magenta (M), yellow (Y) and black (K).

[0050] The printing media receiving section 18 is configured to receive printing media. For example, when the printing media is roll paper, the received roll paper is fed out to a conveying path (not shown) by the conveying motor 164. It should be noted that the printing media receiving section 18 may also have a structure for recycling the printed media, i.e., the printed matter, after printing, such as a structure for winding the roll paper.

[0051] Next, the function blocks of the printer control unit 11 of the first printer 1A will be described. It should be noted that in the first embodiment, the cases in which the first printer 1A is started upon receiving a start instruction from the operator, the first printer 1A instructs the second printer 1B to start, and the second printer 1B instructs the third printer 1C to start will be described.

[0052] The printer control unit 11 has a start instruction receiving unit 111, a designation receiving unit 112, an operator receiving unit 113, a timing unit 114, a start control unit 115, a start sequence storage unit 116, and a proficiency storage unit 117 as functional blocks.

[0053] Specifically, the processor 11A executes the control program stored in the memory 11B, functioning as a start instruction receiving unit 111, a designation receiving unit 112, an operator receiving unit 113, a timing unit 114, and a start control unit 115. Furthermore, the processor 11A executes the control program stored in the memory 11B, causing the memory 11B to function as a start sequence storage unit 116 and a skill level storage unit 117.

[0054] The startup sequence storage unit 116 stores the identification information of the following printer NX. The following printer NX refers to printer 1 that started after the first printer 1A. In this embodiment, the following printer NX is, for example, the second printer 1B.

[0055] When the designated acceptance unit 112 accepts the designation of the follower printer NX, the designated acceptance unit 112 stores the identification information of the accepted follower printer NX in the startup sequence storage unit 116.

[0056] The boot sequence storage unit 116 corresponds to an example of the "boot sequence storage area".

[0057] The term "follow printer NX" corresponds to an example of "follow printing device".

[0058] The skill level storage unit 117 stores skill level information that establishes a correspondence between the operator's skill level UM and the first maintenance time TM1. The first maintenance time TM1 represents the time required for maintenance operations performed after the initial action is executed. Maintenance operations performed after the initial action include, for example, setting the print media in the print media container 18 and checking the nozzles of the print head 161.

[0059] The higher the operator's proficiency level (UM), the shorter the first maintenance time (TM1). For example, the first maintenance time (TM1) is 4 minutes for a beginner and 2 minutes for a proficient operator.

[0060] The start instruction receiving unit 111 receives the start instruction from the operator via the printer input unit 14. For example, the printer input unit 14 has a start button, and when the start button is pressed by the operator, the start instruction receiving unit 111 receives the start instruction from the operator.

[0061] The designation acceptance unit 112 accepts the designation of the printer NX from the operator via the printer input unit 14. For example, the printer input screen is displayed on the touch panel of the printer input unit 14, and the designation of the printer NX is accepted based on the operator's touch operation on the printer input screen.

[0062] The printer input screen displays, for example, an image representing a second printer 1B and an image representing a third printer 1C. If the operator touches the image representing the second printer 1B, the designation receiving unit 112 accepts the designation to set the printer NX to the second printer 1B. If the operator touches the image representing the third printer 1C, the designation receiving unit 112 accepts the designation to set the printer NX to the third printer 1C.

[0063] The operator receiving unit 113 accepts the assignment of the operator's skill level UM for maintenance operations. The operator receiving unit 113 stores the accepted operator's skill level UM as skill information corresponding to the first maintenance time TM1 in the skill level storage unit 117.

[0064] The timing unit 114 keeps track of the first elapsed time TQ1 from the time the start instruction receiving unit 111 receives the start instruction from the operator.

[0065] When the start control unit 115 designates the second printer 1B as a follower printer NX that starts after the first printer 1A, the start control unit 115 performs start instruction processing to output a start instruction to the second printer 1B.

[0066] Specifically, in the startup instruction processing, the startup control unit 115 takes the moment when the first printer 1A receives the startup instruction as the starting point, and outputs a startup instruction to the second printer 1B at a second startup time calculated based on the first initial action time TP1 required for the initial action of the first printer 1A, the first maintenance time TM1 required for the maintenance operation performed after the first printer 1A performs the initial action, and the second initial action time TP2 required for the initial action of the second printer 1B.

[0067] More specifically, when the second printer 1B is designated as the follower printer NX, the start control unit 115 calculates the first start time difference TS1 from the time the first printer 1A receives the start instruction to the second start time using the formula (1) shown below. Then, when the first start time difference TS1 is reached after the first elapsed time TQ1, the start control unit 115 outputs the start instruction to the second printer 1B.

[0068] TS1=TP1+TM1-TP2 (1)

[0069] It should be noted that the first initial action time TP1 represents the time required for the initial action of the first printer 1A. The first maintenance time TM1 represents the time required for maintenance operations performed after the first printer 1A performs its initial action. The second initial action time TP2 represents the time required for the initial action of the second printer 1B.

[0070] In addition, Equation (1) is the same as "Equation (A)".

[0071] In this embodiment, the first initial action time TP1 and the second initial action time TP2 are, for example, 3 minutes.

[0072] In addition, when the start control unit 115 calculates the first start time difference TS1, if the first elapsed time TQ1 is greater than or equal to the first start time difference TS1, it outputs a start instruction to the second printer 1B.

[0073] In addition, when the start instruction receiving unit 111 receives the start instruction from the operator, the start control unit 115 performs an initial action to switch the first printer 1A to a printable state.

[0074] Next, the differences between the function blocks of the printer control unit 11 of the second printer 1B and the function blocks of the printer control unit 11 of the first printer 1A will be explained below.

[0075] In the printer control unit 11 of the second printer 1B, the startup sequence storage unit 116 stores the identification information of the printer 1 that is started after the second printer 1B as the identification information of the following printer NX. In this embodiment, the following printer NX is, for example, the third printer 1C.

[0076] In addition, in the printer control unit 11 of the second printer 1B, the start instruction receiving unit 111 receives the start instruction from the start control unit 115 of the first printer 1A via the printer communication unit 12.

[0077] Additionally, in the printer control unit 11 of the second printer 1B, the operator receiving unit 113 receives the operator's proficiency UM from the start control unit 115 of the first printer 1A via the printer communication unit 12. Then, the operator receiving unit 113 stores it as proficiency information corresponding to the establishment of the second maintenance time TM2 in the proficiency storage unit 117.

[0078] In addition, in the printer control unit 11 of the second printer 1B, the timing unit 114, via the printer communication unit 12, counts the second elapsed time TQ2 from the start instruction receiving unit 111 receiving the start instruction from the start control unit 115 of the first printer 1A.

[0079] In addition, in the printer control unit 11 of the second printer 1B, the start control unit 115 starts at the moment when the second printer 1B receives the start instruction, and outputs a start instruction to the third printer 1C at a third start time calculated based on the second initial operation time TP2 required for the initial operation of the second printer 1B, the second maintenance time TM2 required for the maintenance operation performed after the second printer 1B performs the initial operation, and the third initial operation time TP3 required for the initial operation of the third printer 1C.

[0080] Specifically, when the third printer 1C is designated as the follower printer NX, the start control unit 115 calculates the second start time difference TS2 from the time the second printer 1B receives the start instruction to the time of the third start using the formula (2) shown below. Then, when the second start time difference TS2 is reached in the second elapsed time TQ2, the start control unit 115 outputs the start instruction to the third printer 1C.

[0081] TS2=TP2+TM2-TP3 (2)

[0082] It should be noted that the second initial action time TP2 represents the time required for the initial action of the second printer 1B. The second maintenance time TM2 represents the time required for maintenance operations performed after the second printer 1B performs its initial action. The third initial action time TP3 represents the time required for the initial action of the third printer 1C.

[0083] In this embodiment, the third initial action time TP3 is, for example, 3 minutes.

[0084] In addition, in the printer control unit 11 of the second printer 1B, when the start control unit 115 calculates the second start time difference TS2, if the second elapsed time TQ2 is greater than or equal to the second start time difference TS2, it outputs a start instruction to the third printer 1C.

[0085] In addition, in the printer control unit 11 of the second printer 1B, the start control unit 115 performs an initial action to switch the second printer 1B to a printable state when the start instruction receiving unit 111 receives a start instruction from the first printer 1A.

[0086] Next, the differences between the function blocks of the printer control unit 11 of the third printer 1C and the function blocks of the printer control unit 11 of the second printer 1B will be explained below.

[0087] In the printer control unit 11 of the third printer 1C, the start sequence storage unit 116, the proficiency storage unit 117, the designated acceptance unit 112, the operator acceptance unit 113, and the timing unit 114 do not operate.

[0088] In the printer control unit 11 of the third printer 1C, the start instruction receiving unit 111 receives the start instruction from the start control unit 115 of the second printer 1B via the printer communication unit 12.

[0089] In the printer control unit 11 of the third printer 1C, the start control unit 115 performs an initial action to switch the third printer 1C to a printable state when the start instruction receiving unit 111 receives a start instruction from the second printer 1B.

[0090] Next, refer to Figure 2 as well as Figure 3 An example of the operation of the first printer 1A, the second printer 1B, and the third printer 1C will be described.

[0091] Figure 2 as well as Figure 3 The horizontal axis represents time T.

[0092] Figure 2 This is a timing diagram illustrating an example of the operation of printing system 100A. Figure 2 The following explanation addresses the case where the operator is a skilled worker. Specifically, the first maintenance time TM1, the second maintenance time TM2, and the third maintenance time TM3 are, for example, 2 minutes each. In this case, the first maintenance time TM1, the second maintenance time TM2, and the third maintenance time TM3 are recorded as first maintenance time TM1A, second maintenance time TM2A, and third maintenance time TM3A, respectively.

[0093] In addition, the first initial action time TP1, the second initial action time TP2, and the third initial action time TP3 are each, for example, 3 minutes. Therefore, the first start time difference TS1 and the second start time difference TS2 are calculated to be 2 minutes (=3 minutes + 2 minutes - 3 minutes) by Equation (1) and Equation (2), respectively.

[0094] like Figure 2 As shown, at time T10, the first printer 1A receives the start instruction from the operator and begins to perform the initial actions. Additionally, the first printer 1A begins timing for the first elapsed time TQ1.

[0095] Next, at time T11, the first printer 1A determines that the first elapsed time TQ1 has reached the first start time difference TS1 and outputs a start instruction to the second printer 1B. Then, the second printer 1B begins to perform the initial operation. In addition, the second printer 1B begins timing for the second elapsed time TQ2.

[0096] Time T11 corresponds to an example of the "second start time".

[0097] Next, at time T12, the first printer 1A completes its initial operation and transitions to a printable state. Additionally, maintenance operations performed by the operator begin in the first printer 1A.

[0098] The period from time T10 to time T12 corresponds to the first initial action time TP1.

[0099] Next, at time T13, the second printer 1B determines that the second elapsed time TQ2 has reached the second start time difference TS2, and outputs a start instruction to the third printer 1C. Then, the third printer 1C begins to perform the initial actions.

[0100] Time T13 corresponds to an example of the "third start-up moment".

[0101] Next, at time T14, the maintenance operation performed by the operator in the first printer 1A is completed. Meanwhile, the second printer 1B completes its initial operation and transitions to a printable state. Also, the maintenance operation performed by the operator begins in the second printer 1B.

[0102] The period from time T11 to time T14 corresponds to the second initial action time TP2. The period from time T12 to time T14 corresponds to the first maintenance time TM1A.

[0103] Next, at time T15, the maintenance operation performed by the operator is completed in the second printer 1B. Meanwhile, the third printer 1C completes its initial operation and transitions to a printable state. Also, the maintenance operation performed by the operator begins in the third printer 1C.

[0104] The period from time T13 to time T15 corresponds to the third initial action time TP3. The period from time T14 to time T15 corresponds to the second maintenance time TM2A.

[0105] Next, at time T16, in the third printer 1C, the maintenance operation performed by the operator is completed.

[0106] The period from time T15 to time T16 corresponds to the third maintenance time TM3A.

[0107] like Figure 2 As shown, in the first printer 1A, the second printer 1B, and the third printer 1C, the total time PT1 required for the initial actions and maintenance operations to be completed is 9 minutes. (Refer to...) Figure 10 As will be described later, in the existing printing system 100C, the total time PT3 required for the initial actions to be completed and the maintenance operations to be completed in the first printer 1A, the second printer 1B and the third printer 1C is 15 minutes.

[0108] Therefore, compared with the existing printing system 100C, the time required to complete the initial action and maintenance operation can be shortened in the first printer 1A, the second printer 1B and the third printer 1C.

[0109] Next, refer to Figure 10 The operation of the existing printing system 100C will be explained.

[0110] The existing printing system 100C includes a first printer 1A, a second printer 1B, and a third printer 1C. However, in the existing printing system 100C, the printer control unit 11 of each of the first printer 1A, the second printer 1B, and the third printer 1C does not have a reference... Figure 1 The functional blocks other than the start instruction receiving unit 111 are described. In other words, in the existing printing system 100C, the first printer 1A, the second printer 1B, and the third printer 1C each perform initial actions and transition to a printable state after the printer input unit 14 receives a start instruction from the operator.

[0111] Figure 10 The horizontal axis represents time T. Figure 10 This is a timing diagram illustrating an example of the operation of an existing printing system 100C. Figure 10 The following explanation addresses the case where the operator is a skilled worker. Specifically, the first maintenance time TM1A, the second maintenance time TM2A, and the third maintenance time TM3A are, for example, 2 minutes each.

[0112] like Figure 10 As shown, at time T30, the first printer 1A receives the start instruction from the operator and begins to perform the initial actions.

[0113] Next, at time T31, the first printer 1A completes its initial operation and transitions to a printable state. Additionally, maintenance operations performed by the operator begin in the first printer 1A.

[0114] The period from time T30 to time T31 corresponds to the first initial action time TP1.

[0115] Next, at time T32, the first printer 1A finishes the maintenance operation performed by the operator, and the second printer 1B begins to perform initial actions after receiving the start instruction from the operator.

[0116] The period from time T31 to time T32 corresponds to the first maintenance time TM1A.

[0117] Next, at time T33, the second printer 1B completes its initial operation and transitions to a printable state. Additionally, maintenance operations performed by the operator begin in the second printer 1B.

[0118] The period from time T32 to time T33 corresponds to the second initial action time TP2.

[0119] Next, at time T34, the second printer 1B finishes the maintenance operation performed by the operator, and the third printer 1C begins to perform initial actions after receiving the start instruction from the operator.

[0120] The period from time T33 to time T34 corresponds to the second maintenance time TM2A.

[0121] Next, at time T35, the third printer 1C completes its initial operation and transitions to a printable state. Additionally, maintenance operations performed by the operator begin in the third printer 1C.

[0122] The period from time T34 to time T35 corresponds to the third initial action time TP3.

[0123] Then, at time T36, the third printer 1C completed the maintenance operation performed by the operator.

[0124] The period from time T35 to time T36 corresponds to the third maintenance time TM3A.

[0125] In addition, such as Figure 10 As shown, during the period from time T32 to time T33, the operator incurs a waiting time TW2, and during the period from time T34 to time T35, the operator incurs a waiting time TW3. Both waiting times TW2 and TW3 are 3 minutes. Therefore, in the existing printing system 100C, due to the incurred waiting times TW2 and TW3, the total time PT3 required for the initial operation to be completed and the maintenance operation to be completed in the first printer 1A, the second printer 1B, and the third printer 1C is compared to... Figure 2 The total time shown is PT1, which is 6 minutes long plus 15 minutes.

[0126] In the following explanation, waiting time TW2 and waiting time TW3 are not distinguished, and it is sometimes recorded as waiting time TW.

[0127] By Figure 10 and Figure 2 In comparison, in the printing system 100A according to the first embodiment, the operator does not experience waiting time TW, thus improving the user's workability.

[0128] Next, refer to Figure 11 This section describes the operation of the existing printing system 100D.

[0129] The existing printing system 100D includes a first printer 1A, a second printer 1B, and a third printer 1C. However, in the existing printing system 100D, the printer control unit 11 of each of the first printer 1A, the second printer 1B, and the third printer 1C does not have a reference... Figure 1 The functional blocks other than the start instruction receiving unit 111 are described. In other words, in the existing printing system 100D, the first printer 1A, the second printer 1B, and the third printer 1C each perform initial actions and transition to a printable state after the printer input unit 14 receives a start instruction from the operator.

[0130] Figure 11 The horizontal axis represents time T. Figure 11 This is a timing diagram illustrating an example of the operation of an existing printing system 100D. Figure 11 The following explanation addresses the case where the operator is a skilled worker. Specifically, the first maintenance time TM1A, the second maintenance time TM2A, and the third maintenance time TM3A are, for example, 2 minutes each.

[0131] exist Figure 11 In the printing system 100D shown, with Figure 10 The difference in the printing system 100C shown is that the operator simultaneously starts the first printer 1A, the second printer 1B, and the third printer 1C.

[0132] like Figure 11 As shown, at time T40, the first printer 1A, the second printer 1B, and the third printer 1C respectively begin to perform initial actions upon receiving the start instruction from the operator.

[0133] Next, at time T41, the first printer 1A, the second printer 1B, and the third printer 1C complete their initial operations and transition to a printable state. Meanwhile, in the first printer 1A, maintenance operations performed by the operator begin.

[0134] The period from time T40 to time T41 corresponds to the first initial action time TP1, the second initial action time TP2, and the third initial action time TP3.

[0135] Then, at time T42, the maintenance operation performed by the operator in the first printer 1A ends, and the maintenance operation performed by the operator begins in the second printer 1B.

[0136] The period from time T41 to time T42 corresponds to the first maintenance time TM1A.

[0137] Next, at time T43, the maintenance operation performed by the operator in the second printer 1B ends, and the maintenance operation performed by the operator begins in the third printer 1C.

[0138] The period from time T42 to time T43 corresponds to the second maintenance time TM2A.

[0139] Next, at time T44, in the third printer 1C, the maintenance operation performed by the operator is completed.

[0140] The period from time T43 to time T44 corresponds to the third maintenance time TM3A.

[0141] In addition, such as Figure 11 As shown, during the period from time T41 to time T42, a power consumption period TR2 occurs in the second printer 1B, resulting in excessive power consumption. During the period from time T41 to time T43, a power consumption period TR3 occurs in the third printer 1C, resulting in excessive power consumption. Therefore, the lifespan of consumables is reduced in both the second printer 1B and the third printer 1C.

[0142] In the following description, without distinguishing between power consumption period TR2 and power consumption period TR3, it is sometimes referred to as power consumption period TR.

[0143] By Figure 11 and Figure 2 In comparison, the printing system 100A according to the first embodiment can suppress TR during power consumption, and thus can suppress the reduction of the lifespan of the consumables of the printer 1.

[0144] Figure 3 This is a timing diagram illustrating another example of the operation of printing system 100A. In Figure 3 The following explanation addresses the case where the operator is a beginner. Specifically, the first maintenance time TM1, the second maintenance time TM2, and the third maintenance time TM3 are, for example, 4 minutes each. In this case, the first maintenance time TM1, the second maintenance time TM2, and the third maintenance time TM3 are recorded as first maintenance time TM1B, second maintenance time TM2B, and third maintenance time TM3B, respectively.

[0145] In addition, the first initial action time TP1, the second initial action time TP2, and the third initial action time TP3 are each, for example, 3 minutes. Therefore, the first start time difference TS1 and the second start time difference TS2 are calculated to be 4 minutes (=3 minutes + 4 minutes - 3 minutes) by Equation (1) and Equation (2), respectively.

[0146] like Figure 3 As shown, at time T20, the first printer 1A receives the start instruction from the operator and begins to perform the initial actions. Additionally, the first printer 1A begins timing for the first elapsed time TQ1.

[0147] Next, at time T21, the first printer 1A completes its initial operation and transitions to a printable state. Additionally, maintenance operations performed by the operator begin in the first printer 1A.

[0148] The period from time T20 to time T21 corresponds to the first initial action time TP1.

[0149] Next, at time T22, the first printer 1A determines that the first elapsed time TQ1 has reached the first start time difference TS1 and outputs a start instruction to the second printer 1B. Then, the second printer 1B begins to perform the initial operation. In addition, the second printer 1B begins timing for the second elapsed time TQ2.

[0150] Time T22 corresponds to an example of the "second start time".

[0151] Next, at time T23, the maintenance operation performed by the operator in the first printer 1A is completed. Meanwhile, the second printer 1B completes its initial operation and transitions to a printable state. Also, the maintenance operation performed by the operator begins in the second printer 1B.

[0152] The period from time T21 to time T23 corresponds to the first maintenance time TM1B. Additionally, the period from time T22 to time T23 corresponds to the second initial action time TP2.

[0153] Next, at time T24, the second printer 1B determines that the second elapsed time TQ2 has reached the second start time difference TS2, and outputs a start instruction to the third printer 1C. Then, the third printer 1C begins to perform the initial actions.

[0154] Time T24 corresponds to an example of the "third start-up moment".

[0155] Next, at time T25, the maintenance operation performed by the operator is completed in the second printer 1B. Meanwhile, the third printer 1C completes its initial operation and transitions to a printable state. Also, the maintenance operation performed by the operator begins in the third printer 1C.

[0156] The period from time T23 to time T25 corresponds to the second maintenance time TM2B. Additionally, the period from time T24 to time T25 corresponds to the third initial action time TP3.

[0157] Next, at time T26, in the third printer 1C, the maintenance operation performed by the operator is completed.

[0158] The period from time T24 to time T26 corresponds to the third maintenance time TM3B.

[0159] like Figure 3 As shown, the total time PT2 required for the initial action and maintenance operation to be completed in the first printer 1A, the second printer 1B, and the third printer 1C is 15 minutes.

[0160] In the following explanation, without distinguishing between total time PT1, total time PT2, total time PT3, and total time PT4, it is sometimes recorded as total time PT.

[0161] like Figure 2 as well as Figure 3 As shown, whether the operator is skilled or a beginner, the second printer 1B and the third printer 1C are started at the appropriate time, thus eliminating operator waiting time TW. Therefore, compared to the existing printing system 100C, the total time PT required for initial actions and maintenance operations to be completed is shortened in the first printer 1A, second printer 1B, and third printer 1C.

[0162] Next, refer to Figures 4 to 6 The processing of the printer control unit 11 of the first printer 1A, the printer control unit 11 of the second printer 1B, and the printer control unit 11 of the third printer 1C will be explained.

[0163] Figure 4 This is a flowchart illustrating an example of the processing of the printer control unit 11 of the first printer 1A.

[0164] like Figure 4 As shown, firstly, in step SA101, the start instruction receiving unit 111 determines whether the start instruction has been received from the operator.

[0165] If the start instruction receiving unit 111 determines that no start instruction has been received from the operator (step SA101; No), the process enters a standby state. If the start instruction receiving unit 111 determines that a start instruction has been received from the operator (step SA101; Yes), the process proceeds to step SA103.

[0166] Then, in step SA103, the timing unit 114 starts timing for the first elapsed time TQ1.

[0167] Next, in step SA105, the start control unit 115 begins to execute the initial action.

[0168] Next, in step SA107, the designated acceptance unit 112 determines whether the operator has accepted the designation for the follower printer NX.

[0169] If the designated acceptance unit 112 determines that the operator has accepted the designation for the follower printer NX (step SA107; Yes), the process proceeds to step SA111. If the designated acceptance unit 112 determines that the operator has not accepted the designation for the follower printer NX (step SA107; No), the process proceeds to step SA109.

[0170] Then, in step SA109, the printer control unit 11 determines whether the startup sequence storage unit 116 stores identification information for the following printer NX.

[0171] If the printer control unit 11 determines that the startup sequence storage unit 116 has not stored the identification information of the following printer NX (step SA109; No), the process returns to step SA107. If the printer control unit 11 determines that the startup sequence storage unit 116 has stored the identification information of the following printer NX (step SA109; Yes), the process proceeds to step SA111.

[0172] Then, in step SA111, the operator acceptance unit 113 determines whether to accept the assignment of the operator's proficiency UM for performing the maintenance operation.

[0173] If the operator receiving unit 113 determines that the request for proficiency level UM has not been accepted (step SA111; No), the process enters a standby state. If the operator receiving unit 113 determines that the request for proficiency level UM has been accepted (step SA111; Yes), the process proceeds to step SA113.

[0174] Then, in step SA113, the start control unit 115 obtains the first maintenance time TM1 from the proficiency storage unit 117.

[0175] Next, in step SA115, the start control unit 115 calculates the first start time difference TS1 using the above formula (1).

[0176] Next, in step SA117, the start control unit 115 determines whether the first elapsed time TQ1 is greater than or equal to the first start time difference TS1.

[0177] If the startup control unit 115 determines that the first elapsed time TQ1 is not greater than or equal to the first startup time difference TS1 (step SA117; No), the process enters the standby state. If the startup control unit 115 determines that the first elapsed time TQ1 is greater than or equal to the first startup time difference TS1 (step SA117; Yes), the process proceeds to step SA119.

[0178] Then, in step SA119, the start control unit 115 outputs a start instruction to the second printer 1B. Additionally, the operator receiving unit 113 sends information indicating the operator's skill level UM to the second printer 1B. Then, the process ends.

[0179] For reference Figure 4 As explained, when the first elapsed time TQ1 is greater than or equal to the first start time difference TS1, the start control unit 115 of the first printer 1A outputs a start instruction to the second printer 1B. Therefore, as referred to Figure 2 as well as Figure 3 As explained, it can output a start instruction to the second printer 1B at the appropriate time.

[0180] Figure 5 This is a flowchart illustrating an example of the processing of the printer control unit 11 of the second printer 1B.

[0181] like Figure 5 As shown, in step SA201, the start instruction receiving unit 111 determines whether a start instruction has been received from the first printer 1A.

[0182] If the start instruction receiving unit 111 determines that a start instruction has not been received from the first printer 1A (step SA201; No), the process enters a standby state. If the start instruction receiving unit 111 determines that a start instruction has been received from the first printer 1A (step SA201; Yes), the process proceeds to step SA203. It should be noted that if the start instruction receiving unit 111 determines that a start instruction has been received from the first printer 1A, the operator receiving unit 113 receives information indicating the operator's skill level UM from the first printer 1A and stores it in the skill level storage unit 117.

[0183] Then, in step SA203, the timing unit 114 starts timing for the second elapsed time TQ2.

[0184] Next, in step SA205, the start control unit 115 begins to execute the initial action.

[0185] Next, in step SA207, the designated acceptance unit 112 determines whether the operator has accepted the designation for the follower printer NX.

[0186] If the designated acceptance unit 112 determines that the operator has accepted the designation for the follower printer NX (step SA207; Yes), the process proceeds to step SA211. If the designated acceptance unit 112 determines that the operator has not accepted the designation for the follower printer NX (step SA207; No), the process proceeds to step SA209.

[0187] Then, in step SA209, the printer control unit 11 determines whether the startup sequence storage unit 116 stores identification information for the following printer NX.

[0188] If the printer control unit 11 determines that the startup sequence storage unit 116 has not stored the identification information of the following printer NX (step SA209; No), the process returns to step SA207. If the printer control unit 11 determines that the startup sequence storage unit 116 has stored the identification information of the following printer NX (step SA209; Yes), the process proceeds to step SA211.

[0189] Next, in step SA211, the start control unit 115 obtains the second maintenance time TM2 from the proficiency storage unit 117.

[0190] Next, in step SA213, the start control unit 115 calculates the second start time difference TS2 using the above formula (2).

[0191] Next, in step SA215, the start control unit 115 determines whether the second elapsed time TQ2 is greater than or equal to the second start time difference TS2.

[0192] If the startup control unit 115 determines that the second elapsed time TQ2 is not greater than or equal to the second startup time difference TS2 (step SA215; No), the process enters the standby state. If the startup control unit 115 determines that the second elapsed time TQ2 is greater than or equal to the second startup time difference TS2 (step SA215; Yes), the process proceeds to step SA217.

[0193] Then, in step SA217, the start control unit 115 outputs a start instruction to the third printer 1C. Additionally, the operator receiving unit 113 sends information indicating the operator's skill level UM to the third printer 1C. Then, the process ends.

[0194] For reference Figure 5 As explained, when the second elapsed time TQ2 is greater than or equal to the second start time difference TS2, the start control unit 115 of the second printer 1B outputs a start instruction to the third printer 1C. Therefore, as referred to Figure 2 as well as Figure 3 As explained, it can output a start instruction to the third printer 1C at the appropriate time.

[0195] Figure 6 This is a flowchart illustrating an example of the processing of the printer control unit 11 of the third printer 1C.

[0196] like Figure 6As shown, in step SA301, the start instruction receiving unit 111 determines whether a start instruction has been received from the second printer 1B.

[0197] If the startup instruction receiving unit 111 determines that a startup instruction has not been received from the second printer 1B (step SA301; No), the process enters a standby state. If the startup instruction receiving unit 111 determines that a startup instruction has been received from the second printer 1B (step SA301; Yes), the process proceeds to step SA303.

[0198] Then, in step SA303, the start control unit 115 begins to execute the initial action. After the initial action is completed, the process ends.

[0199] The above is for reference only. Figures 1 to 6 , Figure 10 as well as Figure 11 As described, the printing system 100A according to the first embodiment includes: a first printer 1A, which performs an initial operation and transitions to a printable state upon receiving a start instruction; and a second printer 1B, which performs an initial operation and transitions to a printable state upon receiving a start instruction. When the second printer 1B is designated as a follower printer NX that starts after the first printer 1A, a start instruction processing is performed to output a start instruction to the second printer 1B. In the start instruction processing, starting from the moment the first printer 1A receives the start instruction, the start instruction is output to the second printer 1B at a second start time calculated based on a first initial operation time TP1 required for the initial operation of the first printer 1A, a first maintenance time TM1 required for maintenance operations performed after the first printer 1A performs the initial operation, and a second initial operation time TP2 required for the initial operation of the second printer 1B.

[0200] According to this structure, starting from the moment the first printer 1A receives the start instruction, a start instruction is output to the second printer 1B at the second start time calculated based on the first initial operation time TP1, the first maintenance time TM1, and the second initial operation time TP2. Therefore, the second printer 1B can be started at the appropriate time. Thus, the operator's waiting time TW can be suppressed. Furthermore, since the period of excessive power consumption TR can be suppressed, the reduction in the lifespan of consumables can be prevented.

[0201] Furthermore, in the printing system 100A, the first printer 1A includes: a start instruction receiving unit 111 that receives a start instruction; a designation receiving unit 112 that receives the designation of a follower printer NX; a timing unit 114 that times a first elapsed time TQ1 from the time the first printer 1A receives the start instruction; and a start control unit 115 that performs start instruction processing. When a second printer 1B is designated as the follower printer NX, the start control unit 115 calculates the first start time difference TS1 from the time the first printer 1A receives the start instruction to the second start time using the following formula (A).

[0202] TS1 = TP1 + TM1 - TP2(A)

[0203] In equation (A), TP1 represents the first initial action time, TM1 represents the first maintenance time, TP2 represents the second initial action time, and TS1 represents the first start time difference. When the first elapsed time TQ1 reaches the first start time difference TS1, the start instruction is output to the second printer 1B.

[0204] According to this structure, when the second printer 1B is designated as the follower printer NX, the first start time difference TS1 from the time the first printer 1A receives the start instruction to the second start time is calculated using equation (A). When the first start time difference TS1 is reached after the first elapsed time TQ1, the start instruction is output to the second printer 1B, thus enabling the second printer 1B to start at the appropriate time. Therefore, the operator's waiting time TW can be suppressed. In addition, since the power consumption period TR that generates excessive power consumption can be suppressed, the reduction in the lifespan of consumables can be suppressed.

[0205] In addition, in the printing system 100A, when the start control unit 115 calculates the first start time difference TS1, if the first elapsed time TQ1 is greater than or equal to the first start time difference TS1, it outputs a start instruction to the second printer 1B.

[0206] According to this structure, when the first elapsed time TQ1 is greater than or equal to the first start time difference TS1, a start instruction is output to the second printer 1B, thus enabling the second printer 1B to start at the appropriate time. Therefore, the operator's waiting time TW can be suppressed. Furthermore, since the period of excessive power consumption TR can be suppressed, the reduction in the lifespan of consumables can be prevented.

[0207] In addition, in the printing system 100A, the first printer 1A includes: an operator receiving unit 113, which receives the designation of the operator's skill level UM for performing maintenance operations; and a skill level storage unit 117, which stores skill level information that establishes a correspondence between the operator's skill level UM and a first maintenance time TM1. The start control unit 115 obtains the first maintenance time TM1 corresponding to the operator's skill level UM based on the skill level information, and uses the obtained first maintenance time TM1 to calculate the first start time difference TS1.

[0208] According to this structure, since the first maintenance time TM1 corresponding to the operator's proficiency UM is obtained based on proficiency information, an appropriate first maintenance time TM1 can be determined. Furthermore, since the first start-up time difference TS1 is calculated using the obtained first maintenance time TM1, an appropriate first start-up time difference TS1 can be calculated. Therefore, the second printer 1B can be started at the appropriate time. Thus, the operator's waiting time TW can be suppressed. Additionally, since the period of excessive power consumption TR can be suppressed, the reduction in the lifespan of consumables can be suppressed.

[0209] In addition, in the printing system 100A, the memory 11B of the first printer 1A has a start sequence storage unit 216 that stores information of the follower printer NX. When the start sequence storage unit 216 stores information of the follower printer NX and the designation receiving unit 112 receives an instruction indicating that the follower printer NX is not designated, the start instruction unit 215 gives an instruction to start the output of the follower printer NX stored in the start sequence storage unit 216 as the follower printer NX.

[0210] According to this structure, the instruction to start the output of the follower printer NX stored in the startup sequence storage unit 216 as the follower printer NX is so that even if the operator does not specify the follower printer NX, the instruction to start the output of the appropriate follower printer NX can be given.

[0211] In addition, the printing system 100A includes a third printer 1C. When the third printer 1C receives a start instruction, it performs an initial action and transitions to a printable state. When the third printer 1C is designated as a follower printer NX that starts after the second printer 1B, a start instruction is issued to the third printer 1C through a start instruction processing. In the start instruction processing, starting from the moment when the second printer 1B receives the start instruction, and at a third start time calculated based on the second initial action time TP2, the second maintenance time TM2 required for maintenance operations performed after the second printer 1B performs its initial action, and the third initial action time TP3 required for the initial action of the third printer 1C, a start instruction is output to the third printer 1C.

[0212] According to this structure, starting from the moment the second printer 1B receives the start instruction, a start instruction is output to the third printer 1C at the third start time calculated based on the second initial operation time TP2, the second maintenance time TM2, and the third initial operation time TP3. Therefore, the third printer 1C can be started at the appropriate time. Thus, the operator's waiting time TW can be suppressed. Furthermore, since the period of excessive power consumption TR can be suppressed, the reduction in the lifespan of consumables can be prevented.

[0213] The first printer 1A according to the first embodiment is a printer that performs an initial operation and transitions to a printable state upon receiving a start instruction. It includes: a printer communication unit 12, which is communicatively connected to a second printer 1B that performs an initial operation and transitions to a printable state upon receiving a start instruction; a start instruction receiving unit 111 that receives start instructions; a designation receiving unit 112 that receives designations for a follower printer NX that starts after the first printer 1A; a timing unit 114 that times a first elapsed time TQ1 from receiving the start instruction; and a start control unit. 115, when the second printer 1B is designated as the follower printer NX, performs a start instruction processing to output a start instruction to the second printer 1B. In the start instruction processing, the start control unit 115 takes the moment when the first printer 1A receives the start instruction as the starting point and outputs a start instruction to the second printer 1B at a second start time calculated based on the first initial action time TP1 required for the initial action of the first printer 1A, the first maintenance time TM1 required for the maintenance operation performed after the first printer 1A performs the initial action, and the second initial action time TP2 required for the initial action of the second printer 1B.

[0214] According to this structure, starting from the moment the first printer 1A receives the start instruction, a start instruction is output to the second printer 1B at the second start time calculated based on the first initial operation time TP1, the first maintenance time TM1, and the second initial operation time TP2. Therefore, the second printer 1B can be started at the appropriate time. Thus, the operator's waiting time TW can be suppressed. Furthermore, since the period of excessive power consumption TR can be suppressed, the reduction in the lifespan of consumables can be prevented.

[0215] The printer 1 start-up control method according to the first embodiment is a printer 1 start-up control method for starting a first printer 1A and a second printer 1B. When the first printer 1A receives a start-up instruction, it performs an initial action and moves to a printable state. When the second printer 1B receives a start-up instruction, it performs an initial action and moves to a printable state. When the second printer 1B is designated as a follower printer NX that starts after the first printer 1A, a start-up instruction processing is performed to output a start-up instruction to the second printer 1B. In the start-up instruction processing, starting from the moment when the first printer 1A receives the start-up instruction, a start-up instruction is output to the second printer 1B at a second start-up time calculated based on a first initial action time TP1 required for the initial action of the first printer 1A, a first maintenance time TM1 required for the maintenance operation performed after the initial action of the first printer 1A, and a second initial action time TP2 required for the initial action of the second printer 1B.

[0216] According to this structure, starting from the moment the first printer 1A receives the start instruction, a start instruction is output to the second printer 1B at the second start time calculated based on the first initial operation time TP1, the first maintenance time TM1, and the second initial operation time TP2. Therefore, the second printer 1B can be started at the appropriate time. Thus, the operator's waiting time TW can be suppressed. Furthermore, since the period of excessive power consumption TR can be suppressed, the reduction in the lifespan of consumables can be prevented.

[0217] It should be noted that in the printing system 100A according to the first embodiment, the first printer 1A, the second printer 1B, and the third printer 1C are described as being connected in a manner that allows them to communicate with each other, but this is not a limitation. As long as the first printer 1A and the second printer 1B are connected in a manner that allows them to communicate with each other, and the second printer 1B and the third printer 1C are connected in a manner that allows them to communicate with each other, it is acceptable.

[0218] Furthermore, in the printing system 100A according to the first embodiment, the case where the first printer 1A, the second printer 1B, and the third printer 1C are connected to each other in a communicable manner via a LAN has been described, but this is not a limitation. For example, the first printer 1A, the second printer 1B, and the third printer 1C may also be connected to each other in a communicable manner via a WAN. Alternatively, the first printer 1A, the second printer 1B, and the third printer 1C may also be connected to each other in a communicable manner via the Internet. Furthermore, the first printer 1A, the second printer 1B, and the third printer 1C may also be connected to each other in a communicable manner via wireless communication.

[0219] In addition, in the printing system 100A according to the first embodiment, the first printer 1A outputs a start instruction to the second printer 1B, and the second printer 1B outputs a start instruction to the third printer 1C, but it is not limited to this.

[0220] The first printer 1A may also output start instructions to the second printer 1B and the third printer 1C respectively. In this case, the designated receiving unit 112 of the first printer 1A, for example, accepts the second printer 1B as a follower printer NX of the first printer 1A, and accepts the third printer 1C as a follower printer NX of the second printer 1B. In addition, if the start control unit 115 of the first printer 1A outputs a start instruction to the third printer 1C when the second elapsed time TQ2 is greater than or equal to the second start time difference TS2.

[0221] In this case, the first printer 1A accepts various instructions from the operator, while the second printer 1B and the third printer 1C do not accept instructions from the operator, thus simplifying the processing of the second printer 1B and the third printer 1C.

[0222] Second Implementation Method

[0223] Next, the printing system 100B according to the second embodiment will be described.

[0224] Figure 7 This is a diagram illustrating an example of the structure of the printing system 100B according to the second embodiment.

[0225] The following is a main explanation Figure 7 The printing system 100B according to the second embodiment shown is... Figure 1 The differences between the printing system 100A involved in the first embodiment shown are as follows.

[0226] like Figure 7 As shown, the printing system 100B includes a printer 1 and a terminal device 2. The printer 1 includes a first printer 1A, a second printer 1B, and a third printer 1C.

[0227] The first printer 1A, the second printer 1B, the third printer 1C, and the terminal device 2 are connected to each other via the network NW in a manner that allows them to communicate with each other.

[0228] Next, terminal device 2 will be described.

[0229] like Figure 7 As shown, the terminal device 2 includes a terminal control unit 21, a terminal communication unit 22, a terminal storage unit 23, a terminal input unit 24, and a terminal display unit 25. The terminal device 2 is, for example, a personal computer.

[0230] Terminal device 2 outputs start instructions to the first printer 1A, the second printer 1B and the third printer 1C respectively.

[0231] Terminal device 2 corresponds to an example of "start control device".

[0232] The terminal control unit 21 includes a processor 21A such as a CPU, a memory 21B such as ROM and RAM, an ASIC, signal processing circuits, etc., and controls various parts of the terminal device 2. The memory 21B stores the control program.

[0233] The terminal control unit 21 performs processing through the cooperation of hardware and software. For example, the processor 21A reads the control program stored in the memory 21B to perform processing, or it performs processing through the functions installed in the ASIC, or it performs processing through signal processing circuitry.

[0234] The terminal control unit 21 includes a start instruction receiving unit 211, a designation receiving unit 212, an operator receiving unit 213, a timing unit 214, a start instruction unit 215, a start sequence storage unit 216, and a proficiency storage unit 217 as function blocks. These function blocks are used to represent the functions implemented by the processor 11A through executing the control program for convenience, and do not represent specific application software or hardware. These function blocks will be described later.

[0235] Under the control of the terminal control unit 21, the terminal communication unit 22 communicates with the printer 1, namely the first printer 1A, the second printer 1B and the third printer 1C, according to the prescribed communication standard.

[0236] The terminal storage unit 23 is equipped with non-volatile memory such as HDD, EEPROM, and SSD to store various data in a rewritable manner.

[0237] The terminal input unit 24 includes input units such as operation switches and touch panels provided on the terminal device 2. It detects operations performed on the user's input units and outputs a detection signal corresponding to the operation to the terminal control unit 21. Based on the input from the terminal input unit 24, the terminal control unit 21 performs processing corresponding to the user's operation.

[0238] The terminal display unit 25 includes a display panel, etc., and under the control of the terminal control unit 21, performs tasks such as displaying information to the display panel.

[0239] Next, the functional blocks of the terminal control unit 21 of the terminal device 2 will be described. It should be noted that, in the second embodiment, the case where the terminal device 2 sequentially starts the first printer 1A, the second printer 1B, and the third printer 1C upon receiving an instruction from the operator will be described.

[0240] The terminal control unit 21 has a start instruction receiving unit 211, a designation receiving unit 212, an operator receiving unit 213, a timing unit 214, a start instruction unit 215, a start sequence storage unit 216, and a proficiency storage unit 217 as functional blocks.

[0241] Specifically, the processor 21A executes the control program stored in the memory 21B, functioning as the start instruction receiving unit 211, the designation receiving unit 212, the operator receiving unit 213, the timing unit 214, and the start instruction unit 215. Furthermore, the processor 21A executes the control program stored in the memory 21B, causing the memory 21B to function as the start sequence storage unit 216 and the skill level storage unit 217.

[0242] The startup sequence storage unit 216 stores the startup sequence of printer 1. When the first printer 1A, the second printer 1B, and the third printer 1C are started in sequence, the second printer 1B is stored as a follower printer NX of the first printer 1A, and the third printer 1C is stored as a follower printer NX of the second printer 1B.

[0243] When the designated acceptance unit 212 accepts the designation of the follower printer NX, the designated acceptance unit 212 stores the identification information of the accepted follower printer NX in the startup sequence storage unit 216.

[0244] The skill level storage unit 217 stores the skill level UM of the operator, corresponding to the first maintenance time TM1 and the second maintenance time TM2. The first maintenance time TM1 represents the time required for maintenance operations after the initial action is performed in the first printer 1A. The second maintenance time TM2 represents the time required for maintenance operations after the initial action is performed in the second printer 1B.

[0245] The start instruction receiving unit 211 receives the printer 1 that is initially started from the operator via the terminal input unit 24. For example, the start instruction receiving unit 211 displays a printer start input screen on the touch panel of the terminal input unit 24, and receives the designation of the printer 1 that is initially started based on the operator's touch operation on the printer start input screen.

[0246] The printer startup input screen displays, for example, an image representing the first printer 1A, an image representing the second printer 1B, and an image representing the third printer 1C. When the operator touches the image representing the first printer 1A, the startup instruction receiving unit 211 accepts the first printer 1A as the initially started printer 1.

[0247] The designation acceptance unit 212 accepts the designation of the follower printer NX from the operator via the terminal input unit 24. The designation acceptance unit 212 accepts the designation of the follower printer NX (e.g., the second printer 1B) that was initially started after the start-up printer 1 (e.g., the first printer 1A) accepted by the start-up instruction acceptance unit 211, and the designation of the follower printer NX (e.g., the third printer 1C) that was started after the second printer 1B, via the terminal input unit 24.

[0248] The designated receiving unit 212 displays a printer input screen on the touch panel of the terminal input unit 24, and accepts the designation of the printer NX based on the operator's touch operation on the printer input screen.

[0249] The printer input screen displays, for example, an image representing a second printer 1B and an image representing a third printer 1C. If the operator touches the image representing the second printer 1B, the designation unit 212 accepts the designation to set the printer NX to the second printer 1B. If the operator touches the image representing the third printer 1C, the designation unit 212 accepts the designation to set the printer NX to the third printer 1C.

[0250] The operator receiving unit 213 accepts the assignment of the operator's skill level UM for maintenance operations. The operator receiving unit 213 stores the accepted operator's skill level UM as skill information corresponding to the first maintenance time TM1 and the second maintenance time TM2 in the skill level storage unit 217.

[0251] The timing unit 214 times a first elapsed time TQ1 from the time when the start instruction receiving unit 211 outputs a start instruction to the first printer 1A. Additionally, the timing unit 214 times a second elapsed time TQ2 from the time when the start instruction is output to the second printer 1B.

[0252] As the printer 1 initially activated by the activation instruction receiving unit 211, the activation instruction unit 215 outputs an activation instruction to the first printer 1A when the first printer 1A is received.

[0253] In addition, when the second printer 1B is designated as the follower printer NX that starts after the first printer 1A, the start instruction unit 215 performs start instruction processing to output a start instruction to the second printer 1B.

[0254] Specifically, in the startup instruction processing, the startup instruction unit 215 takes the moment when the first printer 1A receives the startup instruction as the starting point, and outputs a startup instruction to the second printer 1B at a second startup time calculated based on the first initial action time TP1 required for the initial action of the first printer 1A, the first maintenance time TM1 required for the maintenance operation performed after the first printer 1A performs the initial action, and the second initial action time TP2 required for the initial action of the second printer 1B.

[0255] More specifically, when the second printer 1B is designated as the follower printer NX, the start control unit 115 calculates the first start time difference TS1 from the time the first printer 1A receives the start instruction to the second start time using the formula (1) shown below. Then, when the first elapsed time TQ1 reaches the first start time difference TS1, the start control unit 115 outputs a start instruction to the second printer 1B. For convenience, formula (1) is shown again.

[0256] TS1=TP1+TM1-TP2 (1)

[0257] In addition, when the third printer 1C is designated as the follower printer NX that starts after the second printer 1B, the start instruction unit 215 performs start instruction processing to output a start instruction to the third printer 1C.

[0258] Specifically, in the startup instruction processing, the startup instruction unit 215 starts from the moment when it outputs a startup instruction to the second printer 1B, and outputs a startup instruction to the third printer 1C at a third startup time calculated based on the second initial operation time TP2 required for the initial operation of the second printer 1B, the second maintenance time TM2 required for the maintenance operation performed after the second printer 1B performs the initial operation, and the third initial operation time TP3 required for the initial operation of the third printer 1C.

[0259] More specifically, when the third printer 1C is designated as the follower printer NX of the second printer 1B, the start instruction unit 215 calculates the second start time difference TS2 from the start instruction output to the second printer 1B to the third start time using equation (2) shown below. Then, when the second elapsed time TQ2 reaches the second start time difference TS2, the start instruction unit 215 outputs a start instruction to the third printer 1C. For convenience, equation (2) is shown again.

[0260] TS2=TP2+TM2-TP3 (2)

[0261] The start instruction unit 215 corresponds to an example of the "start control unit".

[0262] Next, printer 1 will be described. Since the first printer 1A, the second printer 1B, and the third printer 1C have substantially the same structure, the structure of the first printer 1A will be described, while the descriptions of the second printer 1B and the third printer 1C will be omitted.

[0263] The first printer 1A includes a printer control unit 11, a printer communication unit 12, a printer storage unit 13, a printer input unit 14, a printer display unit 15, a printing unit 16, an ink supply unit 17, and a printing media container unit 18.

[0264] The printer control unit 11 includes a start control unit 115 as a function block.

[0265] When a start instruction is received from the start instruction unit 215 of the terminal device 2, the start control unit 115 performs an initial action to switch the first printer 1A to a printable state.

[0266] Next, refer to Figure 8 as well as Figure 9 An example of the processing of terminal device 2 will be described.

[0267] Figure 8 as well as Figure 9 These are flowcharts illustrating an example of the processing of the terminal control unit 21 of the terminal device 2.

[0268] like Figure 8 As shown, firstly, in step SB101, the start instruction receiving unit 211 determines whether the operator has received, for example, the first printer 1A as the initially started printer 1.

[0269] If the startup instruction receiving unit 211 determines that the printer 1 that was initially started has not been received from the operator (step SB101; No), the process enters a standby state. If the startup instruction receiving unit 211 determines that the printer 1 that was initially started has been received from the operator (step SB101; Yes), the process proceeds to step SB103.

[0270] Then, in step SB103, the timing unit 214 starts timing for the first elapsed time TQ1.

[0271] Next, in step SB105, the start instruction unit 215 outputs a start instruction to the first printer 1A. It should be noted that the start control unit 115 of the first printer 1A receives the start instruction, performs initial actions, and moves the first printer 1A to a printable state.

[0272] Next, in step SB107, the designation acceptance unit 212 determines whether the operator has accepted the designation of the follower printer NX (e.g., the second printer 1B) started after the first printer 1A and the follower printer NX (e.g., the third printer 1C) started after the second printer 1B.

[0273] If the designated acceptance unit 112 determines that the operator has accepted the designation for the follower printer NX (step SB107; Yes), the process proceeds to step SB111. If the designated acceptance unit 112 determines that the operator has not accepted the designation for the follower printer NX (step SB107; No), the process proceeds to step SB109.

[0274] Then, in step SB109, the terminal control unit 21 determines whether the startup sequence storage unit 116 stores identification information of the following printer NX.

[0275] If the terminal control unit 21 determines that the startup sequence storage unit 116 does not store the identification information of the following printer NX (step SB109; No), the process returns to step SB107. If the terminal control unit 21 determines that the startup sequence storage unit 116 stores the identification information of the following printer NX (step SB109; Yes), the process proceeds to step SB111.

[0276] Then, in step SB111, the operator acceptance unit 213 determines whether to accept the assignment of the operator's proficiency UM for performing the maintenance operation.

[0277] If the operator receiving unit 213 determines that the request for proficiency level UM has not been accepted (step SB111; No), the process enters a standby state. If the operator receiving unit 213 determines that the request for proficiency level UM has been accepted (step SB111; Yes), the process proceeds to step SB113.

[0278] Then, in step SB113, the start instruction unit 215 obtains the first maintenance time TM1 from the proficiency storage unit 217.

[0279] Next, in step SB115, the start instruction unit 215 calculates the first start time difference TS1 using the above formula (1).

[0280] Next, in step SB117, the start instruction unit 215 determines whether the first elapsed time TQ1 is greater than or equal to the first start time difference TS1.

[0281] If the startup instruction unit 215 determines that the first elapsed time TQ1 is not greater than or equal to the first startup time difference TS1 (step SB117; No), the process enters the standby state. If the startup instruction unit 215 determines that the first elapsed time TQ1 is greater than or equal to the first startup time difference TS1 (step SB117; Yes), the process proceeds to step SB119.

[0282] Then, in step SB119, the start instruction unit 215 outputs a start instruction to the second printer 1B. It should be noted that the start control unit 115 of the second printer 1B receives the start instruction, performs the initial action, and moves the second printer 1B to a printable state.

[0283] Next, as Figure 9 As shown, in step SB121, the timing unit 214 starts timing for the second elapsed time TQ2.

[0284] Next, in step SB123, the start instruction unit 215 obtains the second maintenance time TM2 from the proficiency storage unit 217.

[0285] Next, in step SB125, the start instruction unit 215 calculates the second start time difference TS2 using the above formula (2).

[0286] Next, in step SB127, the start instruction unit 215 determines whether the second elapsed time TQ2 is greater than or equal to the second start time difference TS2.

[0287] If the startup instruction unit 215 determines that the second elapsed time TQ2 is not greater than or equal to the second startup time difference TS2 (step SB217; No), the process enters the standby state. If the startup instruction unit 215 determines that the second elapsed time TQ2 is greater than or equal to the second startup time difference TS2 (step SB217; Yes), the process proceeds to step SB219.

[0288] Then, in step SB219, the start instruction unit 215 outputs a start instruction to the third printer 1C. It should be noted that the start control unit 115 of the third printer 1C receives the start instruction, performs initial actions, and transitions the third printer 1C to a printable state. Then, the process ends.

[0289] The above is for reference only. Figures 7 to 9As explained, the printing system 100B according to the second embodiment includes: a first printer 1A, which performs an initial operation and transitions to a printable state upon receiving a start instruction; and a second printer 1B, which performs an initial operation and transitions to a printable state upon receiving a start instruction. When the second printer 1B is designated as a follower printer NX that starts after the first printer 1A, a start instruction processing is performed to output a start instruction to the second printer 1B. In the start instruction processing, starting from the moment the first printer 1A receives the start instruction, a start instruction is output to the second printer 1B at a second start time calculated based on a first initial operation time TP1 required for the initial operation of the first printer 1A, a first maintenance time TM1 required for maintenance operations performed after the first printer 1A performs the initial operation, and a second initial operation time TP2 required for the initial operation of the second printer 1B.

[0290] According to this structure, starting from the moment the first printer 1A receives the start instruction, a start instruction is output to the second printer 1B at the second start time calculated based on the first initial operation time TP1, the first maintenance time TM1, and the second initial operation time TP2. Therefore, the second printer 1B can be started at the appropriate time. Thus, the operator's waiting time TW can be suppressed. Furthermore, since the period of excessive power consumption TR can be suppressed, the reduction in the lifespan of consumables can be prevented.

[0291] Additionally, the printing system 100B includes a terminal device 2 that can be communicatively connected to the first printer 1A and the second printer 1B. The terminal device 2 includes: a designation receiving unit 212 that receives designations following the printer NX; and a start instruction unit 215 that outputs a start instruction to the first printer 1A. Starting from the moment the start instruction is output to the first printer 1A, the second start time is calculated based on the first initial operation time TP1 required for the initial operation of the first printer 1A, the first maintenance time TM1 required for the maintenance operation performed after the first printer 1A performs the initial operation, and the second initial operation time TP2 required for the initial operation of the second printer 1B. At the second start time, the start instruction is output to the second printer 1B.

[0292] According to this structure, starting from the moment the first printer 1A receives the start instruction, a start instruction is output to the second printer 1B at the second start time calculated based on the first initial operation time TP1, the first maintenance time TM1, and the second initial operation time TP2. Therefore, the second printer 1B can be started at the appropriate time. Thus, the operator's waiting time TW can be suppressed. Furthermore, since the period of excessive power consumption TR can be suppressed, the reduction in the lifespan of consumables can be prevented.

[0293] The control method for printer 1 according to the second embodiment is a start-up control method for printer 1 that starts a first printer 1A and a second printer 1B. When the first printer 1A receives a start instruction, it performs an initial action and moves to a printable state. When the second printer 1B receives a start instruction, it performs an initial action and moves to a printable state. When the second printer 1B is designated as a follower printer NX that starts after the first printer 1A, a start instruction processing is performed to output a start instruction to the second printer 1B. In the start instruction processing, starting from the moment when the first printer 1A receives the start instruction, a start instruction is output to the second printer 1B at a second start time calculated based on a first initial action time TP1 required for the initial action of the first printer 1A, a first maintenance time TM1 required for the maintenance operation performed after the initial action of the first printer 1A, and a second initial action time TP2 required for the initial action of the second printer 1B.

[0294] According to this structure, starting from the moment the first printer 1A receives the start instruction, a start instruction is output to the second printer 1B at the second start time calculated based on the first initial operation time TP1, the first maintenance time TM1, and the second initial operation time TP2. Therefore, the second printer 1B can be started at the appropriate time. Thus, the operator's waiting time TW can be suppressed. Furthermore, since the period of excessive power consumption TR can be suppressed, the reduction in the lifespan of consumables can be prevented.

[0295] In the printing system 100B according to the second embodiment, the terminal device 2 is, for example, a personal computer, but is not limited thereto. The terminal device 2 may also be a tablet terminal, a smartphone, or the like.

[0296] In the printing system 100B according to the second embodiment, the terminal device 2 is communicatively connected to the first printer 1A, the second printer 1B, and the third printer 1C via a LAN, but is not limited thereto. The terminal device 2 only needs to be communicatively connected to the first printer 1A, the second printer 1B, and the third printer 1C. For example, the terminal device 2 can also be communicatively connected to the first printer 1A, the second printer 1B, and the third printer 1C via a WAN. Alternatively, the terminal device 2 can also be communicatively connected to the first printer 1A, the second printer 1B, and the third printer 1C via the Internet. Furthermore, the terminal device 2 can also be communicatively connected to the first printer 1A, the second printer 1B, and the third printer 1C via wireless communication.

[0297] It should be noted that the first and second embodiments only illustrate one aspect of the present invention, and can be arbitrarily modified and applied within the scope of the present invention.

[0298] For example, in the first and second embodiments, printing system 100A and printing system 100B respectively include a first printer 1A, a second printer 1B, and a third printer 1C, but are not limited to this. Printing system 100A may have two or more printers 1. Printing system 100A and printing system 100B may each have two printers 1, and printing system 100A and printing system 100B may each have four or more printers 1.

[0299] Furthermore, in the first and second embodiments, an inkjet printer using ink as the printing material is exemplified, but for example, an electronic photo printer using toner as the printing material could also be used.

[0300] Furthermore, for example, when the start-up control method of printer 1 in the first and second embodiments is implemented using a computer included in printer 1 or terminal device 2, the present invention can also be constructed using a program executed by the computer to implement the method, a recording medium in which the program is recorded in a computer-readable manner, or a transmission medium for transmitting the program. As the recording medium, magnetic, optical, or semiconductor storage devices can be used. Specifically, examples include removable or fixed recording media such as floppy disks, HDDs, CD-ROMs (Compact Disk Read Only Memory), DVDs (Digital Versatile Disk), Blu-ray discs, magneto-optical disks, flash memory, and card-type recording media. Alternatively, the recording medium can also be a non-volatile storage device such as RAM, ROM, or HDD, which is an internal storage device included in printer 1.

[0301] Furthermore, the functions of the printer control unit 11 and the terminal control unit 21 can also be implemented using one or more processors or semiconductor chips. For example, the printer control unit 11 and the terminal control unit 21 can also be further equipped with coprocessors such as SoC (System-on-a-Chip), MCU (Micro Control Unit), and FPGA (Field-Programmable Gate Array). Additionally, the printer control unit 11 and the terminal control unit 21 can each utilize both the CPU and the coprocessor in cooperation, or selectively use one of them for various controls.

[0302] In addition, for example, Figure 4 , Figure 5 , Figure 6 , Figure 8 as well as Figure 9 The processing units in the flowchart are divided according to the main processing content for easy understanding of the processing of the printer control unit 11 and the terminal control unit 21. This invention is not limited to the division method or name of the processing units. It is also possible to divide the process into more processing units based on the processing content. Furthermore, it is also possible to divide the process into a single processing unit containing more processes. Additionally, the order of these processes can be appropriately changed without affecting the spirit of this invention.

[0303] in addition, Figure 1 as well as Figure 7The functional units shown represent functional structures, and there are no particular limitations on the specific installation method. That is, it is not necessary to install hardware corresponding to each functional unit separately; a structure in which the functions of multiple functional units are implemented by a single processor executing a program can also be adopted. Furthermore, in the above embodiments, a portion of the functions implemented in software can be implemented in hardware, or a portion of the functions implemented in hardware can be implemented in software. In addition, the specific detailed structures of the printer 1 and the other parts of the terminal device 2 can be arbitrarily changed without departing from the spirit of the present invention.

The startup control unit, starting from the moment it outputs the startup instruction to the first printing device, calculates the second startup time based on the first initial operation time required for the initial operation of the first printing device, the first maintenance time required for the maintenance operation performed after the first printing device performs the initial operation, and the second initial operation time required for the initial operation of the second printing device. At the second startup moment, the startup control unit outputs a startup instruction to the second printing device.

8. A printing apparatus, characterized in that, Upon receiving a start instruction, the printing device performs initial actions to transition to a printable state, wherein the printing device comprises: The communication unit is communicatively connected to a second printing device that, upon receiving an activation instruction, performs initial actions and transitions to a printable state. The activation instruction receiving department accepts the activation instruction. The designated receiving department accepts applications for follow-up printing devices that are started after the printing device. The timing unit keeps track of the elapsed time since receiving the activation instruction; as well as The start control unit, when designating the second printing device as the following printing device, executes a start instruction process that outputs the start instruction to the second printing device. In the startup instruction processing, the startup control unit, starting from the moment the printing device receives the startup instruction, outputs the startup instruction to the second printing device at a second startup time calculated based on a first initial action time required for the initial action of the printing device, a maintenance time required for maintenance operations performed after the initial action of the printing device, and a second initial action time required for the initial action of the second printing device.

9. A method for controlling the start-up of a printing device, characterized in that, This is a method for controlling the start of printing devices, which activates both a first and a second printing device. Upon receiving a start instruction, the first printing device performs an initial action and transitions to a printable state; similarly, upon receiving a start instruction, the second printing device performs an initial action and transitions to a printable state. If the second printing device is designated as a follower printing device that starts after the first printing device, a start instruction process is performed to output the start instruction to the second printing device. In the startup instruction processing, starting from the moment when the first printing device receives the startup instruction, the startup instruction is output to the second printing device at a second startup moment calculated based on the first initial action time required for the initial action of the first printing device, the first maintenance time required for the maintenance operation performed after the first printing device performs the initial action, and the second initial action time required for the initial action of the second printing device.
