[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0010] <Printing system configuration> First, the configuration of this embodiment will be described with reference to Fig. 1. Fig. 1 is a schematic diagram of a printing system 1 of this embodiment.

[0011] 1, the printing system 1 includes a communication device 10 and a label printer 20. The communication device 10 wirelessly connects to the label printer for communication and is capable of transmitting and receiving data to and from the label printer 20.

[0012] The communication device 10 is a communication device (for example, a smartphone or a PC (Personal Computer)) that generates print data (image data to be printed, etc.) and transmits it to the label printer 20 for printing.

[0013] The label printer 20 is a thermal printer (electronic device) that heats a tape (not shown) as a print medium to print images such as characters, marks, figures, and tables. In this embodiment, the label printer 20 is capable of mounting a plurality of types of tape, such as paper tape, fabric transfer tape, and magnetic tape. Furthermore, each of the above-mentioned plurality of types of tape is configured with a plurality of types with different tape widths. For example, the paper tape is configured with eight types of tape widths of 3.5 mm, 6 mm, 9 mm, 12 mm, 18 mm, 24 mm, 36 mm, and 46 mm.

[0014] <Communication device configuration> Next, the functional configuration of the communication device 10 will be described with reference to Fig. 2. Fig. 2 is a block diagram showing the functional configuration of the communication device 10.

[0015] 2, communication device 10 includes a CPU (Central Processing Unit) 11, a RAM (Random Access Memory) 12, a storage unit 13, an operation unit 14, a display unit 15, and a wireless communication unit 16. The various units of communication device 10 are connected to each other via a bus 17.

[0016] CPU (measurement means, identification means, display control means, derivation means, notification means) 11 is a processor that reads out and executes designated programs from among system programs and application programs stored in storage unit 13, and controls the operation of communication device 10 by performing various arithmetic processing. Note that communication device 10 may have multiple processors (multiple CPUs, etc.), and the multiple processes executed by CPU 11 in this embodiment may be executed by the multiple processors. In this case, the multiple processors may be involved in a common process, or the multiple processors may independently execute different processes in parallel.

[0017] The RAM 12 provides a working memory space for the CPU 11 and stores temporary data.

[0018] The storage unit 13 is a non-transitory recording medium readable by the CPU 11 as a computer, and stores programs (system programs and application programs) and various data. The storage unit 13 includes a non-volatile memory such as a hard disk drive (HDD) or a solid state drive (SSD). The programs are stored in the storage unit 13 in the form of computer-readable program codes.

[0019] An example of a program (application program) stored in the storage unit 13 is a printer application 131. The printer application 131 is an application program for generating print data and controlling the printing operation of the label printer 20.

[0020] The data stored in the storage unit 13 includes, for example, a reception sensitivity table 132. The reception sensitivity table 132 is a table used when detecting the type of tape (paper tape, cloth transfer tape, magnetic tape, etc.) attached to the label printer 20 (automatic tape type detection). For example, the reception sensitivity table 132 is composed of a plurality of tables corresponding to each tape width (3.5 mm, 6 mm, 9 mm, 12 mm, 18 mm, 24 mm, 36 mm, 46 mm). In each table, a relative value of radio wave strength (RSSI; Received Signal Strength Indicator) and a tape type are stored in association with each other. The relative value of radio wave strength is a value indicating the difference between the radio wave strength (reference value) when wireless communication is performed between the label printer 20 and the communication device 10 in a state where no tape is attached (a state where no tape is set) and the radio wave strength when wireless communication is performed between the label printer 20 and the communication device 10 in a state where a tape is attached (a state where a tape is set). Here, the signal output from the wireless communication unit 25 of the label printer 20 is reflected by structures inside the printer body, and is output with a reduced signal strength by the reflection loss. The structures that cause this reflection loss include the tape set in the label printer 20, and the relative dielectric constant of each tape varies depending on the tape type and tape width, so the reflection loss varies depending on the presence or absence of tape, the tape type, and the tape width. In other words, the strength of the signal output from the wireless communication unit 25 of the label printer 20 takes a unique value depending on the presence or absence of tape, the tape type, and the tape width, even if the communication distance when wireless communication is performed with the communication device 10 is the same and the communication environment is the same. In this embodiment, taking advantage of this characteristic, the above-mentioned receiving sensitivity table 132 is used to detect the tape type of the tape attached to the label printer 20.

[0021] The operation unit 14 has at least one of an input device such as a touch panel overlaid on the display screen of the display unit 15, a physical button, a pointing device such as a mouse, and a keyboard, and outputs operation information to the CPU 11 in response to an input operation on the input device.

[0022] The display unit 15 includes a display device such as a liquid crystal display, and performs various displays on the display device in accordance with display control signals from the CPU 11.

[0023] The wireless communication unit (wireless communication means) 16 is a wireless communication module that wirelessly connects to the label printer 20 and transmits and receives data to and from the label printer 20. In this embodiment, the wireless communication unit 16 connects to the label printer 20 by, for example, BLE (Bluetooth (registered trademark) Low Energy) communication and transmits and receives data.

[0024] <Label printer configuration> Next, the functional configuration of the label printer 20 will be described with reference to Fig. 3. Fig. 3 is a block diagram showing the functional configuration of the label printer 20.

[0025] 3, the label printer 20 includes a CPU 21, a RAM 22, a storage unit 23, an operation unit 24, a wireless communication unit 25, and a printing unit 26. The various units of the label printer 20 are connected via a bus 27.

[0026] The CPU 21 is a processor that controls each part of the label printer 20. The CPU 21 reads out a specified program from among various programs stored in the storage unit 23, develops the program in the RAM 22, and executes various processes in accordance with the program.

[0027] The RAM 22 provides a working memory space for the CPU 21 and stores temporary data.

[0028] The storage unit 23 is a storage unit from which at least information can be read, such as a ROM (Read Only Memory), etc. However, the storage unit 23 may be a storage unit from which at least information can be read and written, such as a flash memory.

[0029] The operation unit 24 has a power key (not shown), a cut key (not shown), etc. The operation unit 24 accepts operation input from the user by pressing each key, and outputs an operation signal to the CPU 21 based on the operation input.

[0030] The wireless communication unit 25 is a wireless communication module for wirelessly connecting to the communication device 10 and transmitting and receiving data to and from the communication device 10. In this embodiment, the wireless communication unit 25 connects to the communication device 10 by, for example, BLE communication and transmits and receives data.

[0031] The printing unit 26 has a thermal head, a platen roller, a cutter, a tape adapter, a drive unit, etc., all of which are omitted from the illustration, and performs printing on the tape under the control of the CPU 21. Then, under the control of the CPU 21, the printing unit 26 cuts the printed tape with the above-mentioned cutter.

[0032] <Printing system operation> Next, a description will be given of the operation of the printing system 1. As an example, with reference to Figures 4 to 11, a description will be given of the operation in which the CPU 11 of the communication device 10 identifies (detects) the tape type of the tape attached (set) in the label printer 20 and sets the tape attributes related to that tape. To achieve the above operation, the CPU 11 executes the initial setting process shown in Figure 4 and the automatic tape type detection process shown in Figure 9.

[0033] <Initial setting process> FIG. 4 is a flowchart showing a control procedure of the initial setting process. As shown in FIG. 5, the initial setting process is executed when an initial setting button 413 is operated on the menu screen 41 displayed on the display unit 15 of the communication device 10. Here, the menu screen 41 is displayed on the display unit 15 when the printer application 131 is started on the communication device 10. In addition to the initial setting button 413, the menu screen 41 is provided with a label creation button 411, a tape attribute setting button 412, and the like. The label creation button 411 is a button used when creating data (print data) to be printed on a tape. The tape attribute setting button 412 is a button used when setting attributes (e.g., tape width, tape type, etc.) of a tape attached to the label printer 20. The label printer 20 is capable of printing on a tape by acquiring tape attribute information indicating the attributes of the tape together with the above-mentioned print data. In other words, if the attributes of the tape are not set in the communication device 10, the label printer 20 is unable to acquire the tape attribute information and therefore is unable to print on a tape.

[0034] Returning to FIG. 4, when the initial setting process is started, the CPU 11 of the communication device 10 causes the display unit 15 to display the initial setting screen 42 (step S101).

[0035] FIG. 6 is a diagram showing an example of the initial setting screen 42. As shown in FIG. As shown in FIG. 6, the initial setting screen 42 displays message information 421 stating "1. Place the label printer in the same position and environment as when the tape type is automatically detected without setting a tape, and turn on the power." The initial setting screen 42 also displays message information 422 stating "2. Press the calibration button in the same position as when the tape type is automatically detected." By displaying these message information 421 and 422, the user is prompted to set the distance between the communication device 10 and the label printer 20 when the tape type is automatically detected, and to set the environment when the tape type is automatically detected. The initial setting screen 42 also has a calibration button 423 and a back button 424. The calibration button 423 is a button used when performing calibration, that is, when measuring the radio wave intensity when wireless communication is performed between the label printer 20 and the communication device 10 with no tape set. The back button 424 is a button used when returning the screen displayed on the display unit 15 from the initial setting screen 42 to the menu screen 41.

[0036] Returning to FIG. 4, after executing the process of step S101, the CPU 11 determines whether or not the back button 424 has been operated on the initial setting screen 42 (step S102).

[0037] If it is determined in step S102 that the back button 424 has been operated (step S102; YES), the CPU 11 ends the initial setting process.

[0038] Moreover, in step S102, if it is determined that the return button 424 has not been operated (step S102; NO), the CPU 11 determines whether or not the calibration button 423 has been operated (step S103).

[0039] In step S103, if it is determined that the calibration button 423 has not been operated (step S103; NO), the CPU 11 returns the process to the determination process of step S102, and repeats the subsequent processes.

[0040] Furthermore, in step S103, if it is determined that the calibration button 423 has been operated (step S103; YES), the CPU 11 transmits and receives a pseudo signal to and from the label printer 20 via the wireless communication unit 16 (step S104).

[0041] Next, the CPU 11 measures the radio wave intensity (first radio wave intensity) of the pseudo signal received from the label printer 20 via the wireless communication unit 16 (step S105).

[0042] Next, the CPU 11 records the radio wave intensity measured in step S105 as a reference value in the memory unit 13 (step S106). At this time, the CPU 11 displays a dialog box 425 with a message saying "Calibration is complete. Please perform automatic tape type detection without changing the position or environment of the label printer," as shown in Fig. 7.

[0043] Next, as shown in Fig. 8, the CPU 11 sets the automatic tape type detection button 414 below the initial setting button 413 on the menu screen 41 (step S107), and ends the initial setting process. The automatic tape type detection button 414 is a button that is used when executing the automatic tape type detection process (see Fig. 9), which will be described later. In other words, once the above-mentioned calibration has been performed, i.e., once the radio wave intensity has been measured when wireless communication is performed between the label printer 20 and the communication device 10 with no tape set, it becomes possible to execute the automatic tape type detection process.

[0044] <Automatic tape type detection process> FIG. 9 is a flowchart showing a control procedure for the automatic tape type detection process. The automatic tape type detection process is executed when the automatic tape type detection button 414 is operated on the menu screen 41 displayed on the display unit 15 of the communication device 10, as shown in FIG.

[0045] When the automatic tape type detection process is started, the CPU 11 of the communication device 10 causes the display unit 15 to display the automatic tape type detection screen 43 (step S201).

[0046] FIG. 10 is a diagram showing an example of the tape type automatic detection screen 43. As shown in FIG. As shown in FIG. 10, the automatic tape type detection screen 43 displays message information 431 saying "1. Set a tape in the label printer and turn on the power in the same environment as during calibration." The automatic tape type detection screen 43 also displays message information 432 saying "2. Press the detection start button in the same position as when the calibration button was pressed." By displaying these message information 431 and 432, the user is encouraged to maintain the distance between the communication device 10 and the label printer 20 during calibration and to maintain the environment during calibration. The automatic tape type detection screen 43 also has a detection start button 433 and a back button 434. The detection start button 433 is a button used when starting automatic tape type detection. The back button 434 is a button used when returning the screen displayed on the display unit 15 from the automatic tape type detection screen 43 to the menu screen 41.

[0047] Returning to FIG. 9, after executing the process of step S201, the CPU 11 determines whether or not the back button 434 has been operated on the tape type automatic detection screen 43 (step S202).

[0048] If it is determined in step S202 that the back button 434 has been operated (step S202; YES), the CPU 11 ends the automatic tape type detection process.

[0049] Moreover, in step S202, if it is determined that the return button 434 has not been operated (step S202; NO), the CPU 11 determines whether or not the detection start button 433 has been operated (step S203).

[0050] In step S203, if it is determined that the detection start button 433 has not been operated (step S203; NO), the CPU 11 returns the process to the determination process of step S202, and repeats the subsequent processes.

[0051] Furthermore, in step S203, if it is determined that the detection start button 433 has been operated (step S203; YES), the CPU 11 transmits and receives a pseudo signal to and from the label printer 20 via the wireless communication unit 16 (step S204).

[0052] Next, the CPU 11 measures the radio wave intensity (second radio wave intensity) of the pseudo signal received from the label printer 20 via the wireless communication unit 16 (step S205).

[0053] Next, the CPU 11 derives the difference (relative value) between the radio wave strength measured in step S205 and the reference value (radio wave strength when wireless communication is performed between the label printer 20 and the communication device 10 with no tape set) recorded in the memory unit 13 (step S206).

[0054] Next, the CPU 11 acquires information on the tape width of the tape set in the label printer 20 from the label printer 20 (step S207). Here, a plurality of physical switches are provided at the tape attachment position of the label printer 20 for detecting the tape width of the set tape. These switches are set so that the combination of switches to be pressed differs depending on the tape width of the tape set in the label printer 20. In other words, the outer shape of the case of each tape is designed so that a predetermined switch is pressed depending on the tape width. As a result, when the tape is set in the label printer 20, the tape width of the tape is automatically detected depending on the pressing manner of the above-mentioned switches. Then, in the label printer 20, when the communication device 10 performs the automatic tape type detection process, information on the detected tape width is transmitted to the communication device 10. As a result, the CPU 11 is able to acquire information on the tape width of the tape set in the label printer 20 from the label printer 20.

[0055] Next, based on the information about the tape width acquired in step S207, the CPU 11 refers to the receiving sensitivity table 132 corresponding to that tape width, and detects (identifies) the tape type of the tape set in the label printer 20 from the difference (relative value) derived in step S206 (step S208).

[0056] Next, the CPU 11 receives the information regarding the tape width acquired in step S207, The information about the tape type detected in step S208 is set as tape attribute information (step S209). Then, CPU 11 ends the automatic tape type detection process. At this time, CPU 11 displays a dialog box 435 with a message saying "The tape width and tape type of the tape set in the label printer have been set as the tape attributes," as shown in Fig. 11. This saves the user the trouble of operating tape attribute setting button 412 on menu screen 41 and inputting and setting the tape width and tape type of the tape set in the label printer 20 on a tape attribute setting screen (not shown).

[0057] Effect As described above, the communication device 10 includes the wireless communication unit 16 that performs wireless communication with the label printer (electronic device) 20 that can accommodate multiple types of tape (printing media). The CPU 11 of the communication device 10 measures the radio wave intensity (RSSI) when wireless communication is performed with the label printer 20 by the wireless communication unit 16. The CPU 11 detects (identifies) the tape attached to the label printer 20 based on the radio wave intensity (first radio wave intensity) measured when wireless communication is performed with the label printer 20 in a state where no tape is attached, and the radio wave intensity (second radio wave intensity) measured when wireless communication is performed with the label printer 20 in a state where a tape is attached. This eliminates the need for a user to visually check the tape attached to the label printer 20 and identify its attributes, making it easier to detect (identify) the tape.

[0058] Furthermore, the CPU 11 detects (identifies) the tape attached to the label printer 20 based on the difference (relative value) between the radio wave intensity (first radio wave intensity) measured when wireless communication is performed with the label printer 20 in a state where no tape is attached, and the radio wave intensity (second radio wave intensity) measured when wireless communication is performed with the label printer 20 in a state where tape is attached. As a result, if the distance between the communication device 10 and the label printer 20 when wireless communication is performed with the label printer 20 in a state where no tape is attached is the same as the distance between the communication device 10 and the label printer 20 when wireless communication is performed with the label printer 20 in a state where tape is attached, the tape attached to the label printer 20 can be detected regardless of the distance, making the detection of the tape even easier.

[0059] <Other> The above-described embodiment is merely an example of the communication device, the print medium identifying method, and the program according to the present invention, and the present invention is not limited to this. For example, in the above embodiment, in step S206 of the automatic tape type detection process (see FIG. 9), the difference (relative value) between the radio wave intensity measured in step S205 and the reference value recorded in the memory unit 13 is derived, but if the difference is equal to or smaller than a predetermined value, a confirmation screen (not shown) may be displayed on the display unit 15 to prompt the user to check whether or not a tape is attached to the label printer 20.

[0060] In the above embodiment, in step S106 of the initial setting process (see FIG. 4), the radio wave intensity measured in step S105 may be recorded in the memory unit 13 as a reference value, and the distance (reference distance) between the communication device 10 and the label printer 20 derived from the radio wave intensity may be recorded. Then, in step S205 of the automatic tape type detection process (see FIG. 9), when the radio wave intensity is measured, the distance between the communication device 10 and the label printer 20 derived from the radio wave intensity may be derived, and if the difference between the distance and the reference distance exceeds a predetermined threshold, a notification to that effect may be given.

[0061] Furthermore, in the above embodiment, if the tape type detected in step S208 of the automatic tape type detection process (see FIG. 9) is a tape type that can maintain high radio wave strength when wireless communication is performed between the communication device 10 and the label printer 20, it is possible to reduce power consumption, for example, by reducing the frequency of data transmission and reception (number of retries) when wireless communication is performed between the communication device 10 and the label printer 20 during label printing.

[0062] Furthermore, in the above embodiment, a mounting table on which the communication device 10 can be placed may be provided on the housing of the label printer 20. This makes it possible to prevent the distance between the communication device 10 and the label printer 20 from changing between the time of calibration and the time of automatic tape type detection, so that the type of the tape attached to the label printer 20 can be appropriately detected.

[0063] Furthermore, in the above embodiment, the tape was identified based on the difference in radio wave strength when wireless communication was performed between the communication device 10 and the label printer 20, but identification may also be performed based on changes in radio wave strength. That is, it is possible to control the radio wave strength when the label printer 20 performs wireless communication with the communication device 10 so that it changes in a predetermined manner over time, and for the communication device 10 to identify the tape by detecting the difference in the amount of change in the radio wave strength between when a tape is attached to the label printer 20 and when it is not attached.

[0064] In the above description, an example has been disclosed in which the HDD or SSD of the storage unit 13 is used as a computer-readable medium for the program according to the present invention, but the present invention is not limited to this example. As other computer-readable media, information recording media such as flash memory and CD-ROM can be applied. In addition, a carrier wave is also applied to the present invention as a medium for providing data of the program according to the present invention via a communication line.

[0065] Furthermore, the detailed configurations and operations of the components of the communication device 10 and label printer 20 in the above embodiment may of course be modified as appropriate without departing from the spirit and scope of the present invention. [Explanation of symbols]
