The software module of the server 101 will be described. The print data receiving unit 411 controls the LANC 305 to receive the 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, the job owner name, the address information of the sender in the LPR communication, etc. included as the print job attributes, and the data storage unit 412 prints the information of the interpretation result. It 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 the print data stored in the printing apparatus 102, which can be specified by the identifier transferred from the identifier receiving unit 414, using a list.

The reserved print data management unit 413 communicates with the printing apparatus 102 to receive a request for processing such as print execution or deletion of print data based on the managed print data. When a request for processing print data 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 the print data stored in the HDD 304 by the data storage unit 412 or the 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 the print data stored in the HDD 304 by the data storage unit 412, the job control unit 416 sends a command 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 the 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. To send a command.

When control (addition or deletion of print data, execution of printing based on print data, etc.) for print data is executed, the log collection unit 417 collects the contents of processing for print data stored in the HDD 204 or HDD 304 as a log. .. The list is updated by the collected logs, and the deferred print data management unit 413 continuously manages print data 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 the print data transmitted from the server 101 or the mobile terminal 103.

Specifically, when the managed data is stored in the HDD 204, the print data management unit 406 assigns an identifier for uniquely identifying the data in 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 causes the print parameter storage unit 404 to store some or all of the print job attributes stored in the HDD 204, the IP address of the print data transmission source, and the network information of the printing apparatus 102 itself (for example, You may also send (IP address) etc.

The stored data control unit 408 receives the command transmitted from the job control unit 416 of the server 101. As a result, the stored data control unit 408 accepts the print processing and the delete processing based on the print data designated by the received command. Upon receiving the print processing of the print data, the saved data control unit 408 reads the print job attribute and print data of the designated print data from the HDD 204, and displays an instruction to execute the print processing based on the read data. It is sent to the forming unit 403. Upon receiving the print data deletion processing, the stored 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 list information of the reservation print data from the reservation 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. The UI control unit 409 also sends a request to the reserved print data management unit 413 of the server 101 to perform control based on a user input via the UI screen displayed on the display panel of the operation panel 205.

In step S502, 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 makes a determination by comparing the IP address of the transmission source of print data with the registered IP address. As a result of the determination by the determination unit 402, if the transmission source of the print data is the server 101, the process proceeds to step S503. On the other hand, as a result of the determination, if the transmission source of the print data is not the server 101, the process proceeds to step S504.

In step S 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 and print job attributes stored in the RAM 203.

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 it in the RAM 203. Next, the print parameter storage unit 404 stores the print job attributes 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. The print data management unit 406 also 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.

<Processing when the server 101 receives the identifier>
FIG. 6 is a flowchart illustrating processing in the server 101 when the server 101 receives the identifier transmitted from the identifier transmitting 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 newly managed.

In step S602, the reservation 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 or the like of the printing apparatus that has transmitted the identifier with the added identifier. As a result, even when the printing system according to the present exemplary embodiment has a plurality of printing devices, the reserved print data management unit 413 can uniquely identify the print data.

<Execution of processing for reserved print data>
A case where a process for print data managed by the reserved print data management unit 413 is executed will be described with reference to FIG. 7.

FIG. 7A is a flowchart illustrating the process in the printing apparatus 102.

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

In step S703, the UI control unit 409 presents information to the user based on the list information received in step S702, creates a UI screen for the user to input, 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 S704, the UI control unit 409 determines the print data to be processed based on the user input and the content of the process 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 send the print data determined in step S<b>704 and the information indicating the processing content of the print data to the server 101.

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

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

In step S711, the reserved print data management unit 413 controls the LANC 305 to receive the information indicating the print data transmitted in step S705 and the content of the process 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 print data of interest. Then, the reserved print data management unit 413 sends a command to the job control unit 416 to process the print data of interest.

In step S712, the job control unit 416 determines whether the print data of interest is print data stored in the printing apparatus 102. As a result of the determination, when the print data of interest 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, when the print data of interest 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 S713, the job control unit 416 controls the LANC 305 to send a command to the storage data control unit 408 of the printing apparatus 102 to process the print data of interest.

In step S714, the job control unit 416 controls the LANC 305 to receive the notification indicating that the process for the print data of interest has been completed.

If NO in step S712, in step S715, the job control unit 416 sends a command to the save data control unit 415 to process the print data of interest. Next, the saved data control unit 415 executes processing for the print data of interest. For example, when the process performed on the print data of interest is printing, the saved data control unit 415 controls the LANC 305 to send the print data stored in the HDD 304 to the print data receiving unit 401 of the printing apparatus 102. To do. Alternatively, when the process executed on the print data of interest is deletion, the saved data control unit 415 deletes the print data stored in the HDD 304.

In step S716, the reservation print data management unit 413 determines whether all the print data to be processed have been processed. 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 this determination is that processing for all print data to be processed has not been completed, processing returns to step S711.

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

In step S721, the storage data control unit 408 controls the wired NIC 209 to receive 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 this identifier and the processing content for the print data of interest.

In step S722, the print data management unit 406 executes the designation process for the print data of interest.

When the designation process for the print data of interest 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 print data of interest is completed, and the series of processes ends. To do.

<User interface screen>
FIG. 8 is a diagram showing an example of a UI screen for controlling the 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 the reserved print data stored in the server 101, and reference numeral 803 indicates the reserved print data stored in the printing apparatus 102. Reference numerals 804 to 806 denote buttons that are pressed when processing 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 print processing for the selected reservation print data is executed, and the preview image is displayed on the display panel of the operation panel 205. Is displayed in. 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 print processing of 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 source address information of the LPR communication, and the printing apparatus itself.

If the UI control unit 409 creates the UI screen based on the information, the job name and the job owner name can be displayed in the list of the reservation print data displayed on the UI screen. At this time, the print data stored in the printing device is displayed in a different color from the print data stored in the server, or the print device name is added to the beginning of the job name and displayed. May be. As a result, it is possible to easily distinguish between the print data stored in the printing apparatus and the print data stored in the server.

As described above, in the printing apparatus 102 according to the present exemplary embodiment, the print data receiving unit 401 interprets the print data according to the protocol for transmitting the print data. Then, the interpretation result is stored by the print parameter storage unit 404 as a print job attribute. Therefore, it is not necessary for the server 101 side to interpret the print data received by the printing apparatus 102 without passing through the server 101 according to the protocol. 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 to. In this case, the printing apparatus 102 separates the print data received from the PC 100 into print data and print job attributes and saves them in the HDD 204. At this time, the print data management unit 406 assigns an identifier to the print data, so that the server 101 also transmits 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. The print data can be controlled in the same manner as the print data.

Further, 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 system does not support the format of the print data sent to the printing device without going through the server, or the server does not support the protocol used when sending the print data to the printing device without going through the server. This embodiment can be applied to the system. That is, this embodiment may be applied to a system that satisfies at least one of these conditions.

As a result of the determination by the determination unit 402, if the setting conditions are met, the process proceeds to step S906. On the other hand, if the set conditions are not met, the process proceeds to step S905.

In step S905, similarly to the first embodiment (step S504 in FIG. 5 ), a saving process of print data and print parameters (specifically, print job attributes) is executed. 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 deleted without being stored. At this time, the print data management unit 406 issues an identifier that can uniquely identify the print data.

In step S907, the identifier transmitting 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 receiving unit 414 of the server 101.

The above is the processing when print data is received by the printing apparatus 102 of the present embodiment.

The identifier receiving unit 414 of the server 101 controls the LANC 305 to receive the information transmitted by the identifier transmitting 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 thereafter deletes the added identifier from the list item.

As described above, in the present exemplary embodiment, the identifier transmitting 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 without being stored. There is. This allows the log collection unit 417 to collect a log for print data for which processing such as reservation or printing has not been executed according to the settings on the printing apparatus 102 side, and the print data can be managed by the server 101. It will be possible.
