  The print data transmission unit 421 of the PC 100 transmits print data to the server 101 via a wired LAN using LPR. The print data transmission unit 431 of the mobile terminal 103 transmits print data to the printing apparatus 102 via the wireless network using IPP.

  The software module of the server 101 will be described. A print data receiving unit 411 controls the LANC 305 to receive print data transmitted from the PC 100. Then, the data storage unit 412 stores the received print data in the HDD 304. At this time, the print data receiving unit 411 interprets the print job name, job owner name, transmission source address information in LPR communication, and the like included as print job attributes, and the data storage unit 412 prints the interpretation result information. The data may be stored in the HDD 304 in association with the data.

  The print data stored by the data storage unit 412 is managed by the reserved print data management unit 413 using a list. The reserved print data management unit 413 also manages print data stored in the printing apparatus 102 that can be specified by the identifier transferred from the identifier reception unit 414 using a list.

  The reserved print data management unit 413 communicates with the printing apparatus 102 to receive a request regarding processing such as print execution based on the managed print data and deletion of the print data. When a print data processing request managed by the reserved print data management unit 413 is received, the job control unit 416 is notified of the content of the request. The notified job control unit 416 determines whether the print data to be processed is print data stored in the HDD 304 by the data storage unit 412 or print data stored in the HDD 204 of the printing apparatus 102. . As a result of the determination, when the print data to be processed is print data stored in the HDD 304 by the data storage unit 412, the job control unit 416 sends an instruction to the storage data control unit 415 to process the print data. On the other hand, as a result of the determination, when the print data to be processed is print data stored in the HDD 204 of the printing apparatus 102, the job control unit 416 processes the print data in the saved data control unit 408 of the printing apparatus 102. Send instructions to

  When control of print data (addition or deletion of print data, execution of printing based on print data, etc.) is executed, the log collection unit 417 collects the processing contents for the print data stored in the HDD 204 or HDD 304 as a log. . The list is updated by the collected log, and the reserved print data management unit 413 continuously manages the print data by using the updated list.

  Next, the software module of the printing apparatus 102 will be described. The print data receiving unit 401 controls the wired NIC 209 or the wireless NIC 210 to receive print data transmitted from the server 101 or the mobile terminal 103.

  The print data receiving unit 401 determines a protocol based on a physical port or a network port number used at the time of print data transmission, and executes processing corresponding to the determination result on the received print data. . In other words, the print data receiving unit 401 executes processing for separating print data into image data and print job attributes for the print data (print job data format) received from the server 101. On the other hand, the print data receiving unit 401 executes processing for specifying print job attributes for print data (PDF format) received from the mobile terminal 103 in accordance with IPP. This print job attribute may include a print job name, a job owner name, and the like.

  When the print data reception unit 401 receives the print data, the determination unit 402 determines whether the transmission source of the received print data is the server 101. Here, the determination unit 402 may perform the determination based on the IP address of the transmission source of the received print data, for example.

  As a result of the determination by the determination unit 402, when the transmission source of the received print data is the server 101, the image forming unit 403 displays an image on the recording medium based on the image data and the print job attribute separated by the print data reception unit 401. Form.

  On the other hand, as a result of the determination by the determination unit 402, if the transmission source of the received print data is an apparatus other than the server 101, the print parameter storage unit 404 stores the print job attribute specified by the print data reception unit 401 in the HDD 204. . The print data storage unit 405 stores the print data in the HDD 204 and retains the print data in the printing apparatus 102. At this time, the print parameter storage unit 404 may store the address information of the transmission source in the network communication in the print data receiving unit 401 in the HDD 204 in association with the print job attribute.

  A print data management unit 406 manages data stored in the HDD 204 by the print parameter storage unit 404 and the print data storage unit 405. Specifically, when data to be managed is stored in the HDD 204, the print data management unit 406 assigns an identifier for uniquely identifying the data within the printing apparatus. Then, the print data management unit 406 passes the identifier to the identifier transmission unit 407.

  The identifier transmission unit 407 controls the wired NIC 209 to transmit the identifier passed from the print data management unit 406 to the identifier reception unit 414. At this time, the identifier transmission unit 407 includes part or all of the print job attributes stored in the HDD 204 by the print parameter storage unit 404, the IP address of the print data transmission source, and the network information of the printing apparatus 102 itself (for example, IP address) may also be transmitted.

  The saved data control unit 408 receives a command transmitted from the job control unit 416 of the server 101. As a result, the saved data control unit 408 receives print processing and deletion processing based on the print data specified by the received command. When the storage data control unit 408 accepts the print processing of the print data, the storage data control unit 408 reads the print job attribute and the print data of the designated print data from the HDD 204, and outputs an instruction for executing the print processing based on the read data. Send to forming unit 403. When the storage data control unit 408 receives the print data deletion process, the storage data control unit 408 sends a command to the print data management unit 406 to delete the designated print data. Upon receiving the command, the print data management unit 406 deletes the designated print data and the print job attribute corresponding to the print data from the HDD 204.

  The UI control unit 409 receives the reserved print data list information from the reserved print data management unit 413 of the server 101, creates a UI screen based on the list information, and displays the created UI screen on the display panel of the operation panel 205. To do. In addition, the UI control unit 409 transmits a request to the reserved print data management unit 413 of the server 101 so as to perform control based on a user input via a UI screen displayed on the display panel of the operation panel 205.

<Processing when receiving printing data in the printing apparatus 102>
A process when the printing apparatus 102 receives print data will be described with reference to the flowchart of FIG.

  In step S501, the print data reception unit 401 controls the wired NIC 209 or the wireless NIC 210 to receive print data.

  In step S <b> 502, the determination unit 402 determines whether the transmission source of the print data is the server 101 using the network information used when receiving the print data. In this embodiment, the IP address of the server 101 is registered in the RAM 203 in advance, and the determination unit 402 determines by comparing the IP address of the transmission source of the print data with the registered IP address. As a result of the determination by the determination unit 402, if the print data transmission source is the server 101, the process proceeds to step S503. On the other hand, as a result of the determination, if the print data transmission source is not the server 101, the process advances to step S504.

  In step S <b> 503, the print data receiving unit 401 separates the print data into image data and print job attributes, and stores these pieces of information in the RAM 203. Next, the image forming unit 403 executes print processing for recording an image on a recording medium based on the image data stored in the RAM 203 and the print job attribute.

  In step S <b> 504, the print data receiving unit 401 specifies the print job attribute of the print data based on the protocol used when receiving the print data, and stores the print job attribute in the RAM 203. Next, the print parameter storage unit 404 stores the print job attribute stored in the RAM 203 in the HDD 204, and the print data storage unit 405 stores the print data in the HDD 204. When storing the print job attribute and the print data in the HDD 204, the print data management unit 406 issues a new identifier and associates the issued identifier with the print job attribute and the print data. Further, the print data management unit 406 passes the newly issued identifier to the identifier transmission unit 407.

  In step S505, the identifier transmission unit 407 transmits the identifier passed from the print data management unit 406 in step S504 to the identifier reception unit 414 of the server 101 via the network.

<Process when identifier is received by server 101>
FIG. 6 is a flowchart illustrating processing in the server 101 when the server 101 receives the identifier transmitted from the identifier transmission unit 407 of the printing apparatus 102.

  In step S601, the identifier receiving unit 414 controls the LANC 305 to receive an identifier for uniquely identifying the reserved print data that has been newly managed.

  In step S602, the reserved print data management unit 413 adds the identifier received in step S601 to the list item. At this time, the reserved print data management unit 413 may associate the IP address information of the printing apparatus that transmitted the identifier with the added identifier. Thereby, even when the printing system in the present embodiment has a plurality of printing apparatuses, the reserved print data management unit 413 can uniquely identify the print data.

<Execution of processing for reserved print data>
A case where processing for print data managed by the reserved print data management unit 413 is executed will be described with reference to FIG.

  FIG. 7A is a flowchart for explaining processing in the printing apparatus 102.

  In step S701, the UI control unit 409 transmits a request to the server 101 to control the wired NIC 209 and send print data list information.

  In step S <b> 702, the UI control unit 409 controls the wired NIC 209 to receive print data list information transmitted from the server 101. The list information received here may include data such as the job name and job owner name of the print data.

  In step S703, the UI control unit 409 creates a UI screen for presenting information to the user and inputting by the user based on the list information received in step S702, and displays the UI screen on the display panel of the operation panel 205. Details of the UI screen created in step S703 will be described later (see FIG. 8).

  In step S <b> 704, the UI control unit 409 determines print data to be processed based on a user input and the content of processing for the print data. At this time, there may be a plurality of print data to be processed.

  In step S <b> 705, the UI control unit 409 controls the wired NIC 209 to transmit information indicating the print data determined in step S <b> 704 and the content of processing for the print data to the server 101.

  In step S706, the UI control unit 409 updates the UI screen.

  FIG. 7B is a flowchart for describing processing in the server 101 after the UI control unit 409 transmits information to the server 101 in step S705 in FIG.

  In step S711, the reserved print data management unit 413 controls the LANC 305 to receive information indicating the print data transmitted in step S705 and the content of processing for the print data. Then, the reserved print data management unit 413 selects one unprocessed print data among the print data to be processed as the target print data. Then, the reserved print data management unit 413 sends a command to the job control unit 416 to process the target print data.

  In step S <b> 712, the job control unit 416 determines whether the target print data is print data stored in the printing apparatus 102. As a result of the determination, if the target print data is print data stored in the printing apparatus 102, the process proceeds to step S713. On the other hand, as a result of the determination, if the target print data is not the print data stored in the printing apparatus 102 (that is, the print data stored in the server 101), the process proceeds to step S715.

  In step S <b> 713, the job control unit 416 controls the LANC 305 to send an instruction to process the target print data to the saved data control unit 408 of the printing apparatus 102.

  In step S <b> 714, the job control unit 416 controls the LANC 305 to receive a notification indicating that the processing for the target print data has been completed.

  If NO in step S712, in step S715, the job control unit 416 sends an instruction to the storage data control unit 415 to process the target print data. Next, the saved data control unit 415 executes processing for the target print data. For example, when the process executed on the target print data is printing, the saved data control unit 415 controls the LANC 305 to transmit the print data stored in the HDD 304 to the print data reception unit 401 of the printing apparatus 102. To do. Alternatively, when the process executed on the target print data is deletion, the saved data control unit 415 deletes the print data stored in the HDD 304.

  In step S716, the reserved print data management unit 413 determines whether or not the processing for all the print data to be processed has been completed. As a result of the determination, when the processing for all print data to be processed is completed, the series of processing ends. On the other hand, if the result of the determination is that processing for all print data to be processed has not been completed, the process returns to step S711.

  FIG. 7C is a flowchart for describing processing in the printing apparatus 102 after the job control unit 416 transmits a command in step S713 in FIG. 7B.

  In step S721, the saved data control unit 408 controls the wired NIC 209 and receives the command transmitted in S713. Since the command received here includes the identifier issued by the print data management unit 406, the printing apparatus 102 can uniquely identify the print data of interest. The saved data control unit 408 notifies the print data management unit 406 of the identifier and the processing content for the target print data.

  In step S722, the print data management unit 406 executes a designation process for the target print data.

  When the designation process for the target print data is completed, in step S723, the saved data control unit 408 controls the wired NIC 209 to transmit a notification indicating that the designation process for the target print data is completed, and the series of processes ends. To do.

<User interface screen>
FIG. 8 is a diagram illustrating an example of a UI screen for controlling reserved print data, which is created by the UI control unit 409 and displayed on the display panel of the operation panel 205. The UI screen 800 has a list 801 of reserved print data, and the user can select the reserved print data. In the figure, reference numeral 802 indicates reserved print data stored in the server 101, and reference numeral 803 indicates reserved print data stored in the printing apparatus 102. Reference numerals 804 to 806 denote buttons that are pressed when processing is performed on the print data selected in the list 801. For example, when the preview button 804 is pressed, the server 101 or the printing apparatus 102 creates a preview image when the printing process for the selected reserved print data is executed, and the preview image is displayed on the display panel of the operation panel 205. Is displayed. When the delete button 805 is pressed, the selected reserved print data and the corresponding print job attribute data are deleted from the server 101 or the printing apparatus 102. When the print button 806 is pressed, the printing process for the selected print data starts.

  The information received in step S601 includes the identifier issued by the print data management unit 406, the print job name and job owner name included as print job attributes, the address information of the LPR communication source, and the printing apparatus itself. The name may be included. If the UI control unit 409 creates a UI screen based on the information, it is possible to display the job name and job owner name in the list of reserved print data displayed on the UI screen. At this time, the print data retained in the printing device is displayed in a different color from the print data retained in the server, or the name of the printing device is added to the head of the job name. May be. As a result, it is possible to easily distinguish between the print data retained in the printing apparatus and the print data retained in the server.

  As described above, the printing apparatus 102 in this embodiment interprets the print data by the print data receiving unit 401 in accordance with the protocol at the time of print data transmission. The interpretation result is stored as a print job attribute by the print parameter storage unit 404. Accordingly, the print data received by the printing apparatus 102 without going through the server 101 does not need to be interpreted according to the protocol on the server 101 side. Therefore, even if the server 101 does not support the protocol of the print data directly received by the printing apparatus 102, the server 101 can manage the print data.

  In the above description, the case where the printing apparatus 102 receives print data from the server 101 or the mobile terminal 103 has been described. However, for example, a system in which the PC 100 transmits print data directly to the printing apparatus 102 (without passing through the server 101). This embodiment can also be applied. In this case, the printing apparatus 102 separates the print data received from the PC 100 into print data and print job attributes and stores them in the HDD 204. At this time, since the print data management unit 406 allocates an identifier for the print data, the server 101 also sends the print data directly transmitted to the printing apparatus 102 without passing through the server 101 to the printing apparatus 102 via the server 101. Can be controlled in the same manner as the print data.

  In the above description, the case where the server 101 does not support both the format and the protocol for the print data received by the printing apparatus 102 from the mobile terminal 103 has been described. However, the server does not support the system that does not support the format of the print data sent to the printing device without going through the server, or the protocol used when sending the print data to the printing device without going through the server. This embodiment can also be applied to the system. That is, this embodiment may be applied to a system that satisfies at least one of these conditions.

  In step S901, the print data receiving unit 401 controls the wired NIC 209 or the wireless NIC 210 to receive print data.

  In step S <b> 902, the determination unit 402 determines whether the transmission source of the print data is the server 101 using the network information used when receiving the print data, as in the first embodiment. As a result of the determination by the determination unit 402, if the print data transmission source is the server 101, the process advances to step S903. On the other hand, if the result of this determination is that the print data transmission source is not the server 101, the process advances to step S904.

  In step S903, as in the first embodiment (step S503 in FIG. 5), print processing for recording an image on a recording medium based on the received print data is executed.

  In step S <b> 904, the determination unit 402 determines whether the received print data is data that matches a condition preset in the printing apparatus 102. This preset condition is a condition for specifying, for example, print data transmitted by wireless communication or print data transmitted from a specific IP address. As a result of the determination by the determination unit 402, if the setting condition is met, the process proceeds to step S906. On the other hand, if the setting condition is not met, the process proceeds to step S905.

  In step S905, as in the first embodiment (step S504 in FIG. 5), print data and print parameters (specifically, print job attributes) are stored. At this time, the print data management unit 406 issues an identifier that can uniquely identify the print data.

  In step S906, the determination unit 402 creates information indicating that the received print data is to be deleted without being retained. At this time, the print data management unit 406 issues an identifier that can uniquely identify the print data.

  In step S907, the identifier transmission unit 407 controls the wired NIC 209, and transmits the information (including the identifier) created in either step S905 or step S906 to the identifier reception unit 414 of the server 101.

  The above is the processing at the time of print data reception in the printing apparatus 102 of the present embodiment.

  The identifier reception unit 414 of the server 101 controls the LANC 305 to receive information transmitted by the identifier transmission unit 407 of the printing apparatus 102. Subsequently, the reserved print data management unit 413 adds the identifier included in the information to the list item, and immediately deletes the added identifier from the list item.

  As described above, according to the present exemplary embodiment, the identifier transmission unit 407 transmits the information to the server 101 regarding the print data determined by the determination unit 402 of the printing apparatus 102 to be ignored and ignored. Yes. As a result, the log collection unit 417 can collect logs for print data for which processing such as reservation or printing has not been executed according to settings on the printing apparatus 102 side, and the server 101 can manage the print data. It becomes possible.
