[Prior art]
In recent years, there has been known an image forming apparatus (hereinafter referred to as a multifunction peripheral) in which the functions of each apparatus such as a printer, a copy, a facsimile, and a scanner are housed in one casing. This multi-function apparatus is provided with a display unit, a printing unit, an imaging unit, and the like in one casing, and four types of software corresponding to a printer, a copy, a facsimile, and a scanner, respectively. Operates as a copy, facsimile and scanner. Patent Document 1 describes an example of a fusion machine as described above.
[0003]
Such a multifunction peripheral stores document files as stored documents in a document management database (hereinafter referred to as a document management DB), for example. Further, the multifunction peripheral stores thumbnails (Thumbnail) in the document management DB as sample images of stored documents. Thumbnails facilitate the selection of stored documents by, for example, displaying an image sample of the stored document in a small size.
[0004]
The multi-function peripheral is connected to a network device or other multi-function peripheral via a network, and distributes, for example, stored documents and thumbnails stored in the document management DB using a distribution function. Further, the multi-function device uses an output function (printing function or the like) to output, for example, stored documents and thumbnails stored in the document management DB. In order to cope with security problems, the multi-function peripheral often sets passwords for stored documents and thumbnails stored in the document management DB.
[0005]
For example, when a stored document or thumbnail is downloaded from the multifunction peripheral, the network device transmits a document ID for identifying the desired stored document or thumbnail and a password that proves the right to use the stored document or thumbnail to the multifunction peripheral. When outputting the stored document or thumbnail stored in the document management DB of the multi-function peripheral, the network device proves the document ID for identifying the desired stored document or thumbnail and the authority to use the stored document or thumbnail. Send the password to the fusion machine.
[0006]
After performing password authentication, the multi-function peripheral reads the stored document or thumbnail corresponding to the document ID from the document management DB, and supplies the read stored document or thumbnail to the network device. Further, after performing password authentication, the multi-function peripheral reads the stored document or thumbnail corresponding to the document ID from the document management DB, and outputs the stored document.
[0007]
For example, a network device makes a download request or output request for stored documents or thumbnails to a multi-function peripheral by using a browser.

[0058]
In FIG. 3, the network device 100 and the document management service 123 and print service 130 of the MFP 1 exchange data in the XML (eXtensible Markup Language) format. Further, a communication protocol standard called SOAP (Simple Object Access Protocol) is used as a data access protocol.
[0059]
In step S1, the network device 100 transmits the document ID and password of the stored document selected by the user to the document management service 123 of the MFP 1 via the network 200 and the httpd 121 of the NCS 31, thereby obtaining the ticket 124 acquisition request. I do. The ticket acquisition request is made using SOAP and XML.
[0060]
Progressing to step S2 following step S1, the document management service 123 transmits the document ID and password included in the ticket 124 acquisition request received from the network device 100 to the MCS 36, and makes a password authentication request. The password authentication request is made using, for example, a password authentication request function “int mcsCheckPassword (unsignedInt DocId, string password)” that uses the document ID and password as arguments. The MCS 36 performs password authentication using the document ID and password received from the document management service 123.
[0061]

[0066]
In step S6 following step S5, the print service 130 transmits the ticket 124 received in step S5 to the document management service 123, and requests acquisition of a thumbnail ID corresponding to the ticket 124. In step S6, a document ID corresponding to the ticket may be requested, and a thumbnail ID corresponding to the document ID may be acquired later. For example, the thumbnail ID acquisition request is made using a thumbnail ID acquisition function “arrayOfAnyURI getDocumentIdsByThicket (base64Binary ticket)” with the ticket 124 as an argument.
[0067]
Progressing to step S7 following step S6, the document management service 123 checks the validity of the received ticket 124 using the table 126. If the ticket 124 is valid, the document management service 123 checks the table 126 according to the ticket ID included in the ticket 124. The document ID is acquired from the document ID, and the thumbnail ID corresponding to the document ID is transmitted to the print service 130. The thumbnail ID is transmitted from the document management service 123 to the print service 130 as a return value of the thumbnail ID acquisition function, for example.
[0068]
In step S8, the print service 130 transmits the thumbnail ID received in step S7 to the ECS 35, and prints a thumbnail corresponding to the thumbnail ID. For example, the ECS 35 reads the thumbnail from the document management DB included in the HDD 68 or the like using the thumbnail ID and performs print processing.

In step S105 following step S104, the print service 130 requests a job entry from the ECS 35 using a function. Progressing to step S106 following step S105, the ECS 35 transmits success or failure of the job entry to the print service 130 as a return value of the function.
[0073]
Proceeding to step S107 following step S106, the ECS 35 transmits an executability notification to the print service 130 by an event. In step S108 following step S107, the print service 130 requests the ECS 35 to start a job using a function.
[0074]
Proceeding to step S109 following step S108, the ECS 35 transmits a job end notification and job ID of the completed job to the print service 130 as an event. In step S110 following step S109, the print service 130 requests the ECS 35 to close the job using a function.
[0075]
With the event flow as shown in FIG. 5, the print service 130 can perform the thumbnail printing process corresponding to the thumbnail ID received in step S7.
[0076]
In step S <b> 9, the print service 130 transmits the print processing result to the network device 100 via the httpd 121 of the NCS 31 and the network 200. Transmission of the print processing result from the print service 130 to the network device 100 is performed using SOAP and XML. Then, the network device 100 displays the print processing result from the multifunction peripheral 1 on the screen of the network device 100.
[0077]
Therefore, the user can easily print the thumbnails stored in the multifunction peripheral 1 by operating the network device 100. Further, in the MFP 1 of FIG. 3, by using the ticket 124, the thumbnail data itself is not transferred unnecessarily, and waste of resources can be prevented. Note that the multifunction peripheral 1 uses the ticket 124 to print an authenticated thumbnail without notifying the print service 130 of a password.
[0078]
