AI Technical Summary

Problems solved by technology

Storing the same data multiple times does not necessarily exhaust the storage space, so the efficiency of storing data is low
[0008] One of the ways to solve the storage problem is to set up a stronghold server in each stronghold, but this is not cost-effective

Embodiment approach 1

[0103] As mentioned above, in order to solve the problem of memory capacity reduction under the demand of lowering the use cost in the market, one solution is to add new processing on the printer, and it is through the embedded Java(registered trademark) installed on the printer. Small processing that the platform can implement.

[0104] Therefore, in Embodiment 1, the "JA agent" that accepts the print request on the printer judges the necessity of storing the print data, and selects and stores only the data definitely necessary for the search of the print data. Thus, the size of stored data per print job can be reduced.

[0105] In particular, when substantially the same document is printed a plurality of times, it is not necessary to store the same print data more than once.

[0106] Here, in order to determine whether a file to be printed has been printed more than once, a unique object identification number attached to each file by the NTFS file system of Windows (registe...

Embodiment approach 2

[0181] Execution of Embodiment 1 can be achieved by generating the same print data from the same electronic document file. The "page editor" has the function of imposing logical pages on the physical page on the PC, and can generate different print data for one document file.

[0182] use Figure 9 A specific example will be described.

[0183] 900 is a file server, which employs a file system such as NTFS5 that stores pairs of files in association with OIDs. 901 is an electronic document file, and the fact that the history of the confidential file is obtained when printing is clearly indicated by the folder name and access authority of the arranged folder.

[0184] 902 is the OID of the electronic document file 901 . 903 is a client PC, which is connected to the file server 900 through the network, and the files on the file server 900 can be freely viewed and printed as long as the user's access authority allows access.

[0185] 904 is an application program that can inte...

Abstract

The invention provides a printing device, an information processing device, their control method, and a printing management system. It prints data based on an electronic file, and generates management information on the print data. These include: receiving print data and identification information associated with the electronic file; comparing the received print data with registered print data registered in the management device based on the identification information; and registering management information.

Description

technical field [0001] The present invention relates to a printing management system, a printing device, an information processing device and their control methods, which are formed by connecting an information processing device generating print data and a printing device receiving the printing data through a network. Background technique [0002] There is such a system, in the case of leaking confidential information after being printed, in order to trace the printed confidential information, print data and print log information (such as user name) are stored in association and managed (refer to Japanese Patent Application Laid-Open No. 08-147446 Bulletin). In this system, when it is found that confidential information has been disclosed, print data similar to the disclosed words and images are searched, and print log information associated with print data with a high degree of similarity is browsed. Herein, the system is called Job Archive System, hereinafter referred to ...
