[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-341591 [Patent Document 2] Japanese Patent Application Laid-Open No. 2016-137583 Summary of the Invention [Problem to be solved by the invention]

[0004] When attempting to realize a printing device that combines the functions of the printing device disclosed in Patent Document 1 and the printing device disclosed in Patent Document 2, even if the user selects on the selection screen to retain the print job after printing, if the print data stored in the storage unit is set to be automatically deleted at the automatic job deletion timing, the print job will be automatically deleted from the storage unit after the time for retaining the print job in the storage unit has elapsed. Therefore, if the automatic job deletion setting is set, there are cases where the benefit of the user selecting to retain the print data in the storage unit is lost. The proposed invention aims to provide a printing device that can change the display on the display unit depending on whether or not automatic job deletion is set, allowing the user to make appropriate selections on the selection screen. [Means for solving the problem]

[0005] In order to solve the above problem, a printing device according to one aspect of the present disclosure includes a reception unit that receives input operations from a user, a display unit, a printing unit that prints images on sheets, a storage unit that stores print jobs, and a control unit, wherein the control unit performs a first deletion process that executes deletion of print jobs stored in the storage unit at a predetermined automatic job deletion timing, the first deletion process being set to whether or not to execute deletion of print jobs according to an automatic job deletion setting; a print job display process that displays the print jobs stored in the storage unit on the display unit; a print job selection process that selects one or more print jobs from the print jobs displayed by the print job display process by an input operation received via the reception unit; and a print job that stores the print jobs selected by the print job selection process in the storage unit after printing is completed. a retention selection process that displays a selection screen for selecting whether to retain the memory of the print job, and allows selection by an input operation received via the reception unit; a print process that prints an image based on the print job selected by the print job selection process onto a sheet using the printing unit; and a second deletion process that retains the memory of the print job in the storage unit after the print processing has been completed if retaining the memory is selected by the retention selection process, and deletes the print job after the print processing has been completed from the storage unit if deletion is selected by the retention selection process.The control unit does not execute the retention selection process if the automatic job deletion setting is a setting to delete the print job, and executes the retention selection process and displays the selection screen on the display unit if the automatic job deletion setting is a setting to not delete the print job.

[0006] According to the above configuration, if a setting is made to automatically delete print jobs at the automatic job deletion timing, the retention selection process is not executed. Therefore, for example, if an administrator of a printing device sets a setting to automatically delete print jobs, when a non-administrator user prints, the selection screen for setting to retain print jobs after printing is not displayed, so the non-administrator user does not make the setting in a situation where they do not see any benefit. By changing the display on the display unit depending on whether or not the automatic job deletion setting is made, the user can make an appropriate selection on the selection screen.

[0007] Furthermore, a printing device according to an aspect of the present disclosure includes a receiving unit that receives input operations from a user, a display unit, a printing unit that prints images on sheets, a storage unit that stores print jobs, and a control unit, wherein the control unit performs a first deletion process that executes deletion of a print job stored in the storage unit at a predetermined automatic job deletion timing, the first deletion process being set to whether or not to execute deletion of a print job according to an automatic job deletion setting, a print job display process that displays the print jobs stored in the storage unit on the display unit, a print job selection process that selects a print job displayed by the print job display process by an input operation received via the receiving unit, a retention selection process that displays a selection screen that selects whether to retain the print job selected by the print job selection process in the storage unit after printing is completed, and allows the print job selected by the print job selection process to be selected by an input operation received via the receiving unit, and a retention selection process that selects a print job based on the print job selected by the print job selection process. and a second deletion process of, if it is selected by the retention selection process that the storage is retained, retaining the storage of the selected print job in the storage unit after the printing process has been completed, and, if it is selected by the retention selection process that the deletion is completed, deleting the selected print job from the storage unit after the printing process has been completed. After the retention selection process is completed, if the automatic job deletion setting is a setting to execute deletion of the print job and it has been selected by the retention selection process that the storage is retained, the control unit displays on the display unit that the automatic job deletion setting is a setting to execute deletion of the print job after the selection screen is displayed, and if the automatic job deletion setting is a setting to not execute deletion of the print job or if it has been selected by the retention selection process that the deletion is completed, the control unit does not display on the display unit that the automatic job deletion setting is a setting to execute deletion of the print job after the selection screen is displayed.

[0008] According to the above configuration, when the setting for automatically deleting a print job is set and when the user selects to retain the storage by the retention selection process, the display unit displays a message indicating that the automatic job deletion setting is a setting for executing the deletion of the print job. Therefore, the user who selected to retain the storage by the retention selection process can be notified that the setting for automatically deleting the print job is set.

[0009] Furthermore, in a printing device according to one aspect of the present disclosure, after the retention selection process is executed, if the automatic job deletion setting is a setting to execute deletion of a print job and the retention selection process has selected to retain the memory of the print job, the control unit displays on the display unit the timing of the automatic job deletion of the print job for which retention of memory was selected, in addition to the automatic job deletion setting being a setting to execute deletion of a print job.

[0010] According to the above configuration, when a print job is set to be automatically deleted and when the retention selection process selects to retain the storage, the automatic job deletion setting is set to execute the deletion of the print job, and the automatic job deletion timing of the print job selected to retain the storage is displayed on the display unit. Therefore, the user who selected to retain the storage by the retention selection process can be notified of the timing when the print job will be automatically deleted.

[0011] In addition, in the printing device according to an aspect of the present disclosure, the automatic job deletion timing is a predetermined regular time.

[0012] According to the above configuration, print jobs are executed periodically, which prevents the storage capacity of the storage unit from being overwhelmed by print jobs to be stored.

[0013] In addition, a printing device according to one aspect of the present disclosure includes a communication unit that communicates with an external device, wherein the control unit receives a print job from the external device via the communication unit and stores the received print job in the memory unit, the control unit stores the reception time at which the print job was stored in the memory unit, and the automatic job deletion timing is the time when an automatic deletion period has elapsed since the reception time.

[0014] According to the above configuration, a print job is deleted when the automatic deletion period has elapsed since the printing date and time of the image based on the print job. Therefore, print jobs that have not been printed repeatedly can be deleted, and the storage capacity of the storage unit can be prevented from being overwhelmed by print jobs to be held.

[0015] Furthermore, in a printing device according to one aspect of the present disclosure, after the retention selection process is executed, if the automatic job deletion setting is a setting for executing deletion of print jobs and the retention selection process has selected to retain memory, the control unit determines the print job with the earliest automatic job deletion timing among the print jobs selected to retain memory, and displays the automatic job deletion timing of the earliest print job on the display unit.

[0016] According to the above configuration, when a print job is set to be automatically deleted and when retention is selected in the retention selection process, the automatic job deletion timing is displayed for the print job with the earliest automatic job deletion timing among the print jobs set to be retained, thereby making it possible to inform the user of the approximate period until the print job selected to be retained will be automatically deleted.

[0017] In addition, in a printing device according to one aspect of the present disclosure, after the retention selection process is executed, if the automatic job deletion setting is a setting for executing deletion of a print job and the retention selection process has selected to retain the memory, the control unit extends the timing of the automatic job deletion of the print job for which the memory has been selected to retain.

[0018] According to the above configuration, when a print job is set to be automatically deleted and when the user selects to retain the print job by the retention selection process, the automatic job deletion timing for the print job selected to be retained is extended, thereby meeting the needs of the user who selects to retain the print job by the retention selection process.

[0019] In addition, in the printing device according to an aspect of the present disclosure, the control unit executes the retention selection process after executing the print job selection process and before executing the printing process.

[0020] According to the above configuration, after a print job is selected, the retention selection process is executed before the printing process is performed, so that the user can confirm whether or not to retain the print job in the storage unit.

[0021] In addition, in a printing device according to one aspect of the present disclosure, the memory unit stores user identification information for a user who stored a print job in association with the print job, and the control unit further performs an authentication process in which an input operation to log in to the printing device is received via the reception unit and the control unit authenticates the user based on the user identification information entered by the input operation, and in the print job display process, the display unit displays, from among the print jobs stored in the memory unit, a print job that is stored in association with the user identification information of the user authenticated by the authentication process.

[0022] According to the above configuration, the authentication process is executed, and only print jobs of authenticated users are displayed in the print job display process, so that only print jobs stored by the user can be confirmed from among the print jobs stored in the storage unit.

[0023] In addition, a printing device according to one aspect of the present disclosure includes a communication unit that communicates with an external device, and the control unit receives a print job from the external device via the communication unit and stores the received print job in the memory unit. In the print job display process, the control unit displays a print job selection screen including a print job list that is a list of print jobs stored in the memory unit. In the print job selection process, a user selects one or more print jobs from the print job list by performing an input operation on the reception unit.

[0024] According to the above configuration, the printing device receives print jobs from an external device and stores the print jobs in a storage unit. Then, a list of the print jobs stored in the storage unit is displayed on a display unit of the printing device. When performing printing, the list of print jobs stored in the storage unit is presented to the user, allowing the user to check the status of the print jobs stored in the storage unit. [Effects of the Invention]

[0025] According to one aspect of the present disclosure, by changing the display on the display unit depending on whether or not automatic job deletion is set, it is possible to allow the user to make appropriate selections on the selection screen. [Brief explanation of the drawings]

[0027] [Embodiment 1] [General configuration of the multifunction device] FIG. 1 is a perspective view showing the appearance of a printing device according to a first embodiment of the present disclosure. A multi-function peripheral (MFP) 1 shown in FIG. 1 is an example of a printing device and has a print function, a copy function, a scan function, a fax function, and the like. Note that the printing device is not limited to a multi-function peripheral having all of the functions described above, and may be, for example, a multi-function peripheral without a fax function. Hereinafter, the up-down direction, front-rear direction, and left-right direction of the multi-function peripheral 1 will be defined as shown by the arrows in FIG. 1.

[0028] The multifunction device 1 includes a printing unit 2, an image reading unit 3, an operation panel 33, and a touch panel 34. The printing unit 2 has an electrophotographic printing function. The printing method of the printing unit 2 is not limited to electrophotographic printing, and may be inkjet printing. The housing 20 of the printing unit 2 includes a paper feed tray 21 and a paper output tray 22. The paper feed tray 21 can hold multiple sheets of plain paper or the like. The printing unit 2 prints an image on a sheet fed from the paper feed tray 21 and outputs the sheet to the paper output tray 22. Note that the sheets held in the paper feed tray 21 are not limited to plain paper, and may be cardboard or the like.

[0029] The image reading unit 3 has a scanning function. The image reading unit 3 includes a housing 30, a document transport unit 31, and a document cover 32. The document transport unit 31 includes a document tray 31A that can hold multiple documents. The document cover 32 is provided rotatably with respect to the placement table of the housing 30.

[0030] The operation panel 33 and the touch panel 34 are provided on the front surface of the multifunction device 1. The operation panel 33 has the touch panel 34, a cancel key 35A, a home key 35B, a back key 35C, a power key 35D, and the like.

[0031] 2 is a block diagram showing the electrical configuration of the multifunction device 1. The multifunction device 1 includes a printing unit 2, an image reading unit 3, an ASIC 11, a RAM 13, a ROM 14, a non-volatile memory 15, a network I / F 16, and a USB I / F 19.

[0032] The ASIC 11 is equipped with a CPU 12. The CPU 12 is an example of a control unit, and performs overall control of each unit of the multifunction device 1. The ASIC 11 may also be used as the control unit. A program 43 for controlling the multifunction device 1 is stored in the ROM 14. The CPU 12 executes the program 43 using the RAM 13 as a working area. The non-volatile memory 15 is made up of an NVRAM or the like, and stores settings for various processes of the multifunction device 1 and data used for the various processes.

[0033] The network I / F 16 is an example of a communication unit. The multifunction device 1 is connected to a LAN via the network I / F 16 and communicates with the administrator PC 17 and the PC 18. The administrator PC 17 is an example of an external device and is an information terminal operated by an administrator of the multifunction device 1. The PC 18 is an example of an external device and is an information terminal operated by a user other than the administrator. The network I / F 16 may be connected to a network other than a LAN. The administrator PC 17 and the PC 18 may be information terminals other than personal computers, such as smartphones or tablet terminals. In addition, a USB storage 19A is connected to the multifunction device 1 from outside the multifunction device 1 via the USB I / F 19.

[0034] The touch panel 34 has a display unit 34A and a reception unit 34B. The display unit 34A of the touch panel 34 is an example of a display unit and is made up of a liquid crystal display or the like. The operation screen of the multifunction peripheral 1 or the like is displayed on the display unit 34A. The reception unit 34B receives touch operations by the user and detects the position pressed by the user. Note that a liquid crystal display that does not have the reception unit 34B may be used as the display unit. The physical keys 35 are an example of a reception unit and receive input operations from the user.

[0035] The USB storage 19A is an example of a storage unit, and stores print jobs. The print jobs include at least image data 42, and may be provided with user identification information and a job name. The USB storage 19A stores job management information 41, and stores the user identification information and job name for each print job to which the user identification information and job name have been added. The RAM 13 may also be used as a storage unit, and the job management information 41 and the image data 42 for the print job may be stored in the RAM 13.

[0036] [Change settings] A method by which an administrator changes the settings of the multifunction device 1 will be described using Figure 3. Figure 3 illustrates an example in which an administrator changes the settings for the automatic deletion process, which will be described later. The multifunction device 1 functions as a web server for an EWS (Embedded Web Server) when the CPU 12 executes a program 43 stored in the ROM 14. When the administrator of the multifunction device 1 starts a browser on the administrator PC 17 and enters a specific URL for the EWS in the browser's URL input field, a browser screen for setting up the multifunction device 1 is displayed on the display unit of the administrator PC 17.

[0037] When the administrator performs a predetermined operation on the settings browser screen and proceeds with the setting change process (S100: YES), a settings screen related to the automatic deletion process is displayed. When the administrator performs an operation on that settings screen to change the setting to execute the automatic deletion process (S101: YES), the operation information is sent to the multifunction device 1, and the automatic deletion setting 44 stored in the nonvolatile memory 15 is set to ON (S102). As a result, the CPU 12 of the multifunction device 1 is set to enable the automatic deletion process. Furthermore, when the administrator changes the setting on that settings screen to not execute the automatic deletion process (S101: NO), the operation information is sent to the multifunction device 1, and the automatic deletion setting 44 stored in the nonvolatile memory 15 is set to OFF (S103).

[0038] [Print job storage] 4 is a flowchart relating to the process of storing a print job in a storage unit such as the USB storage 19A. In the following description, it is assumed that the print job is stored in the USB storage 19A.

[0039] When the CPU 12 receives a print job from the PC 18 via the network I / F 16 (S200: YES), it determines whether the received print job has user identification information and a job name added (S201). In step S201, if the user identification information and the job name have been added to the print job (S201: YES), the CPU 12 proceeds to processing in step S202, and if the user identification information and the job name have not been added to the print job (S201: NO), it proceeds to processing in step S205.

[0040] In step S202, CPU 12 determines whether accumulated print setting 45 stored in non-volatile memory 15 is on. Accumulated print setting 45 is a setting related to whether accumulated print processing, which will be described in detail later, can be executed, and accumulated print processing can be executed when accumulated print setting 45 is on. The set value of accumulated print setting 45 can be set in the same manner as the setting method for automatic deletion setting 44 shown in FIG. 3. In step S202, if accumulated print setting 45 is on (S202: YES), CPU 12 proceeds to processing of step S203, and if accumulated print setting 45 is off (S202: NO), CPU 12 proceeds to processing of step S205.

[0041] In step S203, CPU 12 stores the print job received from PC 18 in USB storage 19A. CPU 12 stores image data 42 of the print job in USB storage 19A. CPU 12 also adds the job name and user identification information added to the print job to job management information 41, and stores the added job management information 41 in USB storage 19A. In the following step S204, CPU 12 adds the date and time of reception of the print job to job management information 41.

[0042] If it is determined in step S201 that the user identification information and the job name are not added to the print job (S201: NO), or if it is determined in step S202 that the accumulated print setting 45 is turned off (S202: NO), the CPU 12 performs the process of step S205. In step S205, the CPU 12 controls the printing unit 2 to print the image data 42 of the print job received from the PC 18 onto a sheet.

[0043] [Job management information] Fig. 5(A) is a diagram showing an example of job management information 41 after the processing of step S204. Job management information 41A shown in Fig. 5(A) stores, for a print job for which image data 42 is stored in USB storage 19A, the job name and user identification information added to the print job, and the date and time when the print job was received.

[0044] [Storage Printing Processing] The flow of the accumulated printing process will be described with reference to Figures 6-8. When a user who has sent a print job from PC 18 operates the home key 35B or the like of multifunction device 1, a standby screen 90 as shown in Figure 8(A) is displayed on display unit 34A of touch panel 34. Standby screen 90 includes a fax button 51, a copy button 52, a scan button 53, an accumulated printing button 54, a settings button 55, and a user authentication button 56.

[0045] The user authentication button 56 is used when a user logs in or logs out of the multifunction device 1. When the user authentication button 56 is pressed, the CPU 12 starts the processing shown in FIG. 6. In step S300 of FIG. 6, the CPU 12 executes authentication processing. The CPU 12 displays a login screen on the display unit 34A of the touch panel 34, and accepts input of the user's identification information and password using the physical key 35 or the like. When the user inputs their own identification information and password, the CPU 12 compares them with information pre-stored in the authentication DB 46 stored in the non-volatile memory 15. If the information entered by the user matches the information pre-stored in the authentication DB 46, the user can log in to the multifunction device 1. When the user logs in to the multifunction device 1 (S301: YES), the CPU 12 proceeds to the processing of step S302.

[0046] In step S302, the CPU 12 determines whether or not a print job of the logged-in user is stored in the USB storage 19A. The CPU 12 searches for a print job associated with the user identification information of the logged-in user from among the print jobs stored in the job management information 41A of the USB storage 19A. If the search results in a print job associated with the user identification information of the logged-in user (S302: YES), the CPU 12 proceeds to processing in step S303. In step S303, the CPU 12 performs accumulated printing processing. The accumulated printing processing will be described later with reference to FIG. 7.

[0047] If the print job associated with the user identification information of the logged-in user does not exist in the job management information 41A (S302: NO), or if the processing of step S303 is completed, the CPU 12 proceeds to processing of step S304. In step S304, the CPU 12 displays the standby screen 90 on the display unit 34A of the touch panel 34, and proceeds to processing of step S305.

[0048] In step S305, the CPU 12 determines whether or not the store print button 54 has been pressed. If the store print button 54 has been pressed (S305: YES), the CPU 12 proceeds to the process of step S303, and if the store print button 54 has not been pressed (S305: NO), the CPU 12 proceeds to the process of step S306.

[0049] In step S306, the CPU 12 determines whether the logged-in user logs out. If the user performs a predetermined operation to log out of the multifunction peripheral 1 (S306: YES), the CPU 12 ends the processing in Fig. 6, and if the user does not perform a predetermined operation to log out (S306: NO), the CPU 12 displays the standby screen 90 on the display unit 34A of the touch panel 34 (S304).

[0050] The processing of step S303 in Fig. 6 will be described with reference to Fig. 7 and Fig. 8. When the processing shown in Fig. 7 starts, CPU 12 acquires information about the print jobs of the logged-in user from job management information 41A and creates a print job list in step S400. After creating the print job list, CPU 12 proceeds to the processing of step S401.

[0051] In step S401, the CPU 12 executes a print job display process. The CPU 12 displays a job selection screen 91, as shown in FIG. 8B, on the display unit 34A of the touch panel 34. The job selection screen 91 displays a delete button 61, a select all button 62, a print button 63, check boxes 66A-66E, and scroll buttons 64 and 65. The job selection screen 91 shown in FIG. 8B is displayed when a user "UserA" logs in to the multifunction device 1. The print job list created in step S400 is displayed on the left side of FIG. 8B. The print job list in FIG. 8B displays all job names for print jobs whose user identification information is "UserA" in the job management information 41A of FIG. 5A.

[0052] When the CPU 12 displays the job selection screen 91, it executes a print job selection process. The CPU 12 accepts the selection of a print job that the user wishes to delete or print via the acceptance unit 34B of the touch panel 34 or the physical keys 35. When the user selects and presses a print job that the user wishes to delete or print from the print jobs displayed on the job selection screen 91, a check mark is displayed in the check boxes 66A-66E located to the left of each selected print job. When the user presses the select all button 62, a check mark is displayed in the check boxes 66A-66E of all print jobs displayed on the job selection screen 91. When the user presses the delete button 61 or the print button 63, the selection of the print job is confirmed.

[0053] In step S402, the CPU 12 determines whether an instruction has been input using the print button 63 or the delete button 61. The print button 63 is a button for instructing printing of image data 42 for a print job selected by the user. The delete button 61 is a button for instructing deletion of a print job. If an instruction has been input using the print button 63 on the job selection screen 91 (S402: print button), the CPU 12 proceeds to processing in step S403.

[0054] In step S403, the CPU 12 determines whether or not the automatic deletion setting 44 is off. If the automatic deletion setting 44 stored in the nonvolatile memory 15 is off (S403: YES), the CPU 12 proceeds to processing of step S404, and if the automatic deletion setting 44 stored in the nonvolatile memory 15 is on (S403: NO), the CPU 12 proceeds to processing of step S405.

[0055] In step S404, the CPU 12 executes a retention selection process. More specifically, the CPU 12 displays a retention selection screen 92, as shown in FIG. 8C, on the display unit 34A of the touch panel 34. The retention selection screen 92 is a screen that allows the user to select whether to retain the memory of the print job selected by the user after printing is completed, or to delete the print job. The retention selection screen 92 displays a YES button 71 and a NO button 72. The user presses the YES button 71 if they want to retain the memory of the print job even after printing is completed, or presses the NO button 72 if they want to delete the print job after printing is completed. When the user presses the YES button 71 or the NO button 72, the process proceeds to step S405.

[0056] In step S405, the CPU 12 executes printing processing. The CPU 12 controls the printing unit 2 to print the image data 42 for the print job selected by the user on the job selection screen 91. When printing for all print jobs selected on the job selection screen 91 is completed, the CPU 12 proceeds to processing in step S406.

[0057] In step S406, the CPU 12 determines whether or not the YES button 71 has been selected on the storage selection screen 92. If the YES button 71 has not been selected (S406: NO), the CPU 12 proceeds to the process of step S407. That is, if the automatic deletion setting 44 is on (S403: NO) and the storage selection screen 92 has not been displayed, or if the automatic deletion setting 44 is off (S403: YES) and the NO button has been selected on the storage selection screen 92, the CPU 12 proceeds to the process of step S407.

[0058] In step S407, the CPU 12 deletes the print job selected on the job selection screen 91 from the USB storage 19A. The CPU 12 deletes the image data 42 of the print job selected on the job selection screen 91 from the USB storage 19A, deletes information about the print job from the job management information 41A, and stores the job management information 41A after the deletion in the USB storage 19A. When the CPU 12 has finished updating the job management information 41A, it ends the processing of FIG. 7.

[0059] In step S406, if the YES button 71 is selected on the retention selection screen 92 (S406: YES), the CPU 12 determines to retain the memory of the print job selected on the job selection screen 91. The CPU 12 ends the processing of FIG. 7 for the print job selected on the job selection screen 91 without deleting the image data 42 and the like from the USB storage 19A. Because the memory of the print job is retained, the print job will be displayed in the print job list the next time the job selection screen 91 is displayed. For example, retaining the memory of the print job makes it easier to reprint documents that the user prints regularly, such as forms that new patients are asked to fill out at the reception desk.

[0060] In step S402, if an instruction is input using the delete button 61 (S402: delete button), the CPU 12 proceeds to the process of step S408. In step S408, the CPU 12 deletes the image data 42 of the print job selected from the job selection screen 91 from the USB storage 19A, deletes information about the print job from the job management information 41A, and stores the job management information 41A after the deletion in the USB storage 19A.

[0061] Next, in step S409, CPU 12 determines whether or not any print jobs of the logged-in user remain in job management information 41A. That is, CPU 12 determines whether or not any print jobs to be displayed in the print job list remain. If CPU 12 determines that any print jobs of the logged-in user remain in job management information 41A (S409: YES), CPU 12 proceeds to the process of step S401, and if no print jobs of the logged-in user remain in job management information 41A (S409: NO), CPU 12 ends the process of FIG.

[0062] [Automatic deletion process] The flow of the automatic deletion process, which is an example of the first deletion process, will be described using FIG. 9. FIG. 9 is a flowchart related to the automatic deletion process. The automatic deletion process is resident when the automatic deletion setting 44 stored in the non-volatile memory 15 is on. In step S500, the CPU 12 determines whether or not a predetermined automatic deletion timing has arrived. In the example of FIG. 9, the predetermined automatic deletion timing is midnight. When the predetermined automatic deletion timing arrives (S500: YES), the CPU 12 proceeds to the processing of step S501. However, if a user is logged in to the multifunction device 1 at the predetermined automatic deletion timing, the processing may not proceed to the processing of step S501, or the processing may proceed to the processing of step S501 after the user logs out.

[0063] In step S501, the CPU 12 determines whether the automatic deletion setting 44 is on. If the automatic deletion setting 44 stored in the nonvolatile memory 15 is on (S501: YES), the CPU 12 proceeds to processing in step S502. On the other hand, if the automatic deletion setting 44 is off (S501: NO), the CPU 12 ends the processing of FIG.

[0064] In step S502, CPU 12 acquires job management information 41A from USB storage 19A. CPU 12 sequentially deletes print jobs from the acquired job management information 41A (S503-S506). Specifically, in step S503, CPU 12 initializes variable N to 0, and in step S504, increments variable N by 1.

[0065] In step S505, CPU 12 deletes image data 42 of the Nth print job from USB storage 19A and deletes the Nth print job from job management information 41A. CPU 12 stores job management information 41A after deleting the Nth print job in USB storage 19A. Note that Nth here refers to the order in job management information 41A at the start of processing in step S502. In the following processing, even if some print jobs are deleted and some print jobs are moved up in job management information 41A, the processing order of each print job will be described as not changing.

[0066] In step S506, CPU 12 determines whether it has determined whether to retain or delete the storage of a print job for all print jobs stored in job management information 41A. If it has determined that all print jobs stored in job management information 41A have been retained (S506: YES), CPU 12 ends the processing in Fig. 9. If it has not determined that all print jobs stored in job management information 41A have been processed (S506: NO), CPU 12 proceeds to step S504, increments variable N by 1, and starts processing the next print job.

[0067] [Effects of the First Embodiment] According to the multifunction peripheral 1 of the first embodiment described above, the CPU 12 performs the following operations: an automatic deletion process (FIG. 9) that deletes print jobs stored in the USB storage 19A at a predetermined automatic job deletion timing, and whether or not to delete a print job is set according to an automatic job deletion setting; a print job display process (S401) that displays the print jobs stored in the USB storage 19A on the display unit 34A of the touch panel 34; a print job selection process (S402) that selects one or more print jobs from the print jobs displayed by the print job display process by an input operation accepted via the acceptance unit 34B; and a print job selection process (S403) that selects one or more print jobs from the print jobs selected by the print job selection process. The CPU 12 executes a retention selection process (S404) that displays a retention selection screen 92 for selecting whether to retain the storage of the print job in the USB storage 19A after printing is completed, allowing the selection to be made by an input operation accepted via the accepting unit 34B, a print process (S405) that prints an image based on the print job selected in the print job selection process onto a sheet using the printing unit 2, and a process (S407) that retains the storage of the print job in the USB storage 19A after the print processing is completed if retaining the storage is selected in the retention selection process (S406: YES), and deletes the print job from the USB storage 19A after the print processing is completed if deletion is selected in the retention selection process (S406: NO). If the automatic deletion setting 44 is on and the setting is to execute deletion of the print job (S403: NO), the CPU 12 does not execute the retention selection process, and displays the retention selection screen 92 on the display unit 34A if the automatic deletion setting 44 is off and the setting is to not execute deletion of the print job (S403: YES). According to the above configuration, if the automatic job deletion setting 44 is on at the time of automatic job deletion (S403: NO), the retention selection process (S404) is not executed. Therefore, for example, if an administrator of the multifunction peripheral 1 sets a setting to automatically delete print jobs, when a non-administrator user prints, the retention selection screen 92 for setting to retain the print job after printing is not displayed, so the non-administrator user does not make the setting in a situation where they do not see any benefit. By changing the display on the display unit 34A depending on whether the automatic job deletion setting is enabled or disabled, the user can make an appropriate selection on the retention selection screen 92.

[0068] After executing the print job selection process (S402), the CPU 12 also executes the retention selection process (S404) before executing the print process (S405). According to the above configuration, after a print job is selected, the retention selection process is executed before the printing process is performed, so that the user can confirm whether or not to retain the print job in the storage unit.

[0069] In addition, the USB storage 19A stores user identification information for the user who stored the print job in association with the print job. The CPU 12 receives an input operation to log in to the multifunction device 1 via the reception unit 34B, and further executes an authentication process (S300, S301) to authenticate the user based on the user identification information entered by the input operation. In the print job display process, the print job stored in the USB storage 19A in association with the user identification information of the user authenticated by the authentication process is displayed on the display unit 34A. According to the above configuration, the authentication process is executed, and only print jobs of authenticated users are displayed in the print job display process. Therefore, only print jobs stored by the user can be confirmed from among the print jobs stored in the USB storage 19A.

[0070] Furthermore, the CPU 12 receives a print job from the PC 18 via the network I / F 16 (S200), stores the received print job in the USB storage 19A (S203), displays a job selection screen 91 including a print job list that is a list of the print jobs stored in the USB storage 19A on the display unit 34A (S401), and in the print job selection process, the user selects one or more print jobs from the print job list by inputting data into the reception unit 34B (S402). According to the above configuration, the multifunction device 1 receives print jobs from the PC 18 and stores the print jobs in the USB storage 19A. Then, the multifunction device 1 displays a list of print jobs stored in the USB storage 19A on the display unit 34A. When performing printing processing, the list of print jobs stored in the USB storage 19A is presented to the user, allowing the user to check the accumulation status of print jobs in the USB storage 19A.

[0071] [Embodiment 2] Other embodiments of the present disclosure will be described below. For ease of explanation, the same reference numerals will be used to designate components having the same functions as those described in the above embodiment, and the description thereof will not be repeated.

[0072] Fig. 5(B) is a diagram showing an example of job management information 41 in embodiment 2. Job management information 41B shown in Fig. 5(B) stores, for a print job whose image data 42 is stored in USB storage 19A, the job name and user identification information added to the print job, the date and time when the print job was received, and the automatic deletion time.

[0073] FIG. 10 is a flowchart relating to the automatic deletion process according to the second embodiment of the present disclosure. In step S600, the CPU 12 determines whether or not a predetermined automatic deletion timing has arrived. In the example of FIG. 10, the automatic deletion timing is a predetermined regular time, occurring every five minutes. When the predetermined automatic deletion timing arrives (S600: YES), the CPU 12 proceeds to the process of step S601. Note that if a user is logged in to the multifunction peripheral 1 at the predetermined automatic deletion timing, the process may not proceed to step S601.

[0074] In step S601, CPU 12 initializes variable N to 0. In step S602, CPU 12 acquires the current time. In step S603, CPU 12 increments variable N by 1. In step S604, CPU 12 acquires the reception date and time and the automatic deletion time for the Nth print job included in job management information 41B.

[0075] In step S605, the CPU 12 subtracts the reception date and time of the Nth print job acquired in step S604 from the current time acquired in step S602 to calculate the elapsed time from the reception date and time of the Nth print job.

[0076] In step S606, the CPU 12 determines whether the elapsed time calculated in step S605 is greater than the automatic deletion time acquired in step S604. If the elapsed time is greater than the automatic deletion time (S606: YES), the CPU 12 proceeds to processing in step S607, and if the elapsed time is equal to or less than the automatic deletion time (S606: NO), the CPU 12 proceeds to processing in step S608.

[0077] In step S607, CPU 12 deletes image data 42 of the Nth print job from USB storage 19A and deletes the Nth print job from job management information 41B, where Nth refers to the order in job management information 41B at the start of processing in step S601.

[0078] In step S608, CPU 12 determines whether it has determined whether to retain or delete the storage of a print job for all print jobs stored in job management information 41B. If it has determined that all print jobs stored in job management information 41B have been retained (S608: YES), CPU 12 ends the processing in Fig. 10. If it has not determined that all print jobs stored in job management information 41B have been processed (S608: NO), CPU 12 proceeds to step S603, increments variable N by 1, and starts processing the next print job.

[0079] Fig. 11 is a flowchart relating to the accumulated printing process according to the second embodiment of the present disclosure. In the accumulated printing process according to the second embodiment shown in Fig. 11, when an instruction is input using the print button 63 on the job selection screen 91 in step S402 (S402: print button), the process proceeds to step S700 and starts the display process shown in detail in Fig. 12.

[0080] Fig. 12 is a flowchart relating to the display processing executed in step S700 of Fig. 11. When the CPU 12 starts executing the display processing, in step S701 of Fig. 12, the CPU 12 executes a hold selection process similar to step S403 of Fig. 7, and displays a hold selection screen 92, exemplified in Fig. 8(C), on the display unit 34A of the touch panel 34. In the following step S702, the CPU 12 determines whether or not the YES button 71 has been selected on the hold selection screen 92. If the YES button 71 has been selected (S702: YES), the CPU 12 proceeds to the processing of step S703, and if the YES button 71 has not been selected (S702: NO), the CPU 12 ends the processing of Fig. 12.

[0081] In step S703, the CPU 12 determines whether or not the automatic deletion setting 44 is on. If the automatic deletion setting 44 stored in the nonvolatile memory 15 is off, the CPU 12 ends the processing of Fig. 12, and if the automatic deletion setting 44 stored in the nonvolatile memory 15 is on, the CPU 12 proceeds to the processing of step S704.

[0082] In step S704, CPU 12 increases the setting value of the automatic deletion time in job management information 41B by a predetermined time for the print jobs selected on job selection screen 91. For example, if print job 1 and print job 3 are selected on job selection screen 91 shown in Fig. 8(B), the automatic deletion times of print job 1 and print job 3 in job management information 41B shown in Fig. 5(B) are increased by 48 hours, as shown in Fig. 5(C). In Fig. 5(B), the setting values ​​of the automatic deletion times for print job 1 and print job 3 were 24 hours, but in Fig. 5(C), these have each been increased by 48 hours to 72 hours.

[0083] In the next step S705, the CPU 12 determines the print job with the earliest automatic job deletion timing among the print jobs selected on the job selection screen 91. The automatic job deletion timing is the date and time of reception of the print job plus the automatic deletion time. For example, in the job management information 41B illustrated in FIG. 5(C), the automatic job deletion timing for print job 2 is 10:10 AM, March 12, 2022, which is the earliest among the print jobs with user identification information User A.

[0084] In the following step S706, the CPU 12 displays the automatic job deletion timing for the print job with the earliest automatic job deletion timing determined in step S705 on the display unit 34A of the touch panel 34. FIG. 13 shows an example of a warning display screen 93 that displays the automatic job deletion timing. The warning display screen 93 shown in FIG. 13 displays a warning message including the print job with the earliest automatic job deletion timing determined in step S705 and the time until that automatic job deletion timing. The warning display screen 93 in FIG. 13 displays an OK button 81 below the warning message. When the OK button 81 is pressed, the CPU 12 closes the warning display screen 93 and ends the processing in FIG. 12. The warning display screen 93 may display the automatic job deletion timing itself instead of the time until the automatic job deletion timing.

[0085] [Effects of the second embodiment] According to the multifunction peripheral of the second embodiment described above, the CPU 12 performs the following operations: an automatic deletion process (FIG. 10) that deletes a print job stored in the USB storage 19A at a predetermined automatic job deletion timing, and whether or not to delete the print job is set according to an automatic job deletion setting; a print job display process (S401) that displays the print jobs stored in the USB storage 19A on the display unit 34A; a print job selection process (S402) that selects a print job displayed by the print job display process by an input operation accepted via the acceptance unit 34B; and a print job selection process (S403) that selects the print job selected by the print job selection process after printing is completed. a retention selection process (S701) that displays a retention selection screen 92 for selecting whether to retain the storage in the storage unit after completion, and allows selection by an input operation accepted via the acceptance unit 34B; a print process (S402) that prints an image based on the print job selected by the print job selection process onto a sheet using the printing unit 2; and if retaining the storage is selected by the retention selection process (S406: YES), the storage of the selected print job in the USB storage 19A is retained after completion of the print process, and if deleting is selected by the retention selection process (S406: NO), the print job is deleted from the USB storage 19A after completion of the print process (S407). After executing the retention selection process, if the automatic deletion setting 44 is on and the setting is to delete the print job (S703: YES), and if it has been selected by the retention selection process to retain the memory (S702: YES), the CPU 12 displays on the display unit 34A after displaying the retention selection screen 92 that the automatic deletion setting 44 is set to delete the print job (S706, Figure 13), and if the automatic deletion setting 44 is off and the setting is not to delete the print job, or if it has been selected by the retention selection process to delete the memory, the CPU 12 does not display on the display unit 34A after displaying the retention selection screen 92 that the automatic deletion setting 44 is set to delete the print job. According to the above configuration, when the automatic deletion setting 44 is on and the setting is set to automatically delete print jobs (S703: YES), and when the YES button 71 is selected on the retention selection screen 92 (S702: YES), the fact that the automatic deletion process is set to execute deletion of print jobs is displayed on the display unit 34A (S706), as shown in Fig. 13. Therefore, it is possible to inform a user who has selected to retain storage through the retention selection process that the setting is set to automatically delete print jobs.

[0086] Furthermore, after executing the retention selection process, if the automatic deletion setting 44 is set to execute deletion of the print job (S703: YES) and the retention selection process has selected to retain the memory of the print job (S702: YES), the CPU 12 displays on the display unit 34A, as shown in FIG. 13, the automatic job deletion timing of the print job for which retention of memory has been selected, in addition to the setting to execute deletion of the print job (S706). According to the above configuration, when the automatic deletion setting 44 is on and the setting is set to automatically delete a print job (S703: YES), and when the retention selection process selects to retain the storage (S702: YES), in addition to the setting to execute print job deletion, the automatic job deletion timing of the print job for which retention was selected is displayed on the display unit 34A (S706), as shown in Fig. 13. Therefore, the user who selected to retain the storage for the retention selection process can be notified of the timing when the print job will be automatically deleted.

[0087] The automatic job deletion timing is a predetermined regular time (S600). According to the above configuration, print jobs are executed periodically, which prevents the storage capacity of a storage unit such as the USB storage 19A from being overwhelmed by the print jobs to be stored.

[0088] In addition, the CPU 12 receives a print job from the PC 18 via the network I / F 16 (S200), stores the received print job in the USB storage 19A (S203), and stores the reception time when the print job was stored in the USB storage 19A (S203). The automatic job deletion timing is the time when the automatic deletion period has elapsed from the reception time. According to the above configuration, a print job is deleted when the automatic deletion period has elapsed since the date and time of reception of image data 42 based on the print job. Therefore, print jobs that have not been printed repeatedly can be deleted, and it is possible to prevent the storage capacity of a storage unit such as USB storage 19A from being overwhelmed by print jobs to be held.

[0089] Furthermore, after executing the retention selection process (S701), if the automatic deletion setting 44 is on and the setting is to execute deletion of print jobs, and if the retention selection process has selected to retain the memory, the CPU 12 determines the print job with the earliest automatic job deletion timing among the print jobs selected to retain the memory (S705), and displays the earliest automatic job deletion timing of the print job on the display unit 34A (S706). According to the above configuration, when a print job is set to be automatically deleted and when retention is selected in the retention selection process, the automatic job deletion timing is displayed for the print job with the earliest automatic job deletion timing among the print jobs set to be retained, thereby making it possible to inform the user of the approximate period until the print job selected to be retained will be automatically deleted.

[0090] Furthermore, after executing the retention selection process, if the automatic deletion setting 44 is on and the setting is to execute deletion of the print job (S703: YES), and if the retention selection process has selected to retain the memory (S702: YES), the CPU 12 extends the automatic job deletion timing for the print job selected to retain the memory (S704). According to the above configuration, when a print job is set to be automatically deleted and when the user selects to retain the print job by the retention selection process, the automatic job deletion timing for the print job selected to retain the print job is extended, thereby meeting the needs of the user who selects to retain the print job by the retention selection process.

[0091] [Embodiment 3] Other embodiments of the present disclosure will be described below. For ease of explanation, the same reference numerals will be used to designate components having the same functions as those described in the above embodiment, and the description thereof will not be repeated.

[0092] A printing device according to a third embodiment of the present disclosure differs from the second embodiment in that it executes the process shown in Fig. 10 as the automatic deletion process and executes the process shown in Fig. 14 as the display process. Fig. 14 is a flowchart relating to the display process according to the third embodiment of the present disclosure. In the display process shown in Fig. 14, if the automatic deletion setting 44 stored in the nonvolatile memory 15 is on in step S703 (S703: YES), the setting is to automatically delete the print job by the automatic deletion process, and a warning message indicating that the print job will be deleted at a predetermined time is displayed on the display unit 34A of the touch panel 34 (S800), and the process in Fig. 14 ends.

[0093] [Effects of the Third Embodiment] According to the multifunction peripheral of the third embodiment described above, the CPU 12 performs the following operations: an automatic deletion process (FIG. 9) that deletes a print job stored in the USB storage 19A at a predetermined automatic job deletion timing, and whether or not to delete the print job is set according to the automatic job deletion setting; a print job display process (S401) that displays the print jobs stored in the USB storage 19A on the display unit 34A; a print job selection process (S402) that selects a print job displayed by the print job display process by an input operation accepted via the acceptance unit 34B; and a print job selection process (S403) that selects the print job selected by the print job selection process after printing is completed. a retention selection process (S404) that displays a retention selection screen 92 for selecting whether to retain the storage in the storage unit after completion, and allows selection by an input operation accepted via the acceptance unit 34B; a print process (S402) that prints an image based on the print job selected by the print job selection process onto a sheet using the printing unit 2; and if retaining the storage is selected by the retention selection process (S406: YES), the storage of the selected print job in the USB storage 19A is retained after completion of the print process, and if deleting is selected by the retention selection process (S406: NO), the print job is deleted from the USB storage 19A after completion of the print process (S407). After executing the retention selection process, if the automatic deletion setting 44 is on and the setting is to delete the print job (S703: YES), and if it has been selected by the retention selection process to retain the memory (S702: YES), the CPU 12 displays on the display unit 34A (S800) the fact that the automatic deletion setting 44 is set to delete the print job, after displaying the retention selection screen 92 (S701); if the automatic deletion setting 44 is off and the setting is not to delete the print job (S703: NO), or if it has been selected by the retention selection process to delete the memory (S702: NO), the CPU 12 does not display on the display unit 34A the fact that the automatic deletion setting 44 is set to delete the print job, after displaying the retention selection screen 92. According to the above configuration, if the automatic deletion setting 44 is on and the setting is set to automatically delete print jobs (S703: YES), and if the YES button 71 is selected on the retention selection screen 92 (S702: YES), a warning indicating that the automatic deletion process is set to execute deletion of print jobs is displayed on the display unit 34A (S800). Therefore, it is possible to inform a user who has selected to retain storage through the retention selection process that the setting is set to automatically delete print jobs.

[0094] [Modification] In the printing device according to each of the above embodiments, the administrator can change the settings of the multifunction device 1 by having the multifunction device 1 function as a web server for the EWS and displaying a browser screen for setting the multifunction device 1 on the display unit of the administrator PC 17. However, the method by which the administrator of the multifunction device 1 can change the settings of the multifunction device 1 is not limited to this method. For example, the administrator can have a setting screen displayed on the display unit 34A of the touch panel 34, and have input operations related to setting changes received at the reception unit 34B.

[0095] In the printing device according to each of the above embodiments, after a print job to be printed is selected on the job selection screen 91, the retention selection screen 92 is displayed on the display unit 34A of the touch panel 34, but this is not limited to this. For example, a button for selecting whether to retain or delete the print job storage after printing may be further provided on the job selection screen 91. Also, in the printing device according to each of the above embodiments, the retention selection screen 92 is displayed before printing the print job, but the retention selection screen 92 may also be displayed after printing. Also, the standby screen 90, job selection screen 91, and retention selection screen 92 shown in FIGS. 7(A)-(C) are merely examples and are not limited to these.

[0096] In the printing device according to each of the above embodiments, the data structure of job management information 41 is shown in Figures 5(A) and (B), but is not limited to this. The data structure of job management information 41 may be one other than that shown in Figures 5(A) and (B) as long as it includes information for specifying a print job, information for identifying the user who stored the print job, and information indicating whether to retain the storage after printing.
