  • Publication number: 20090237713
    Abstract: A print managing apparatus is provided, which is able to reduce the possibility of information leakage due to the printed material, without implementing a new function in the network printer. When there is a directive to perform printing, the print managing apparatus generates a release key, incorporates the generated release key in the print data, and transfers the print data to the network printer. Then, the print managing apparatus displays on the display device, a screen prompting for a release key that corresponds to the release key, which is printed on a printed medium together with the print data.

  • Publication number: 20070186278
    Abstract: In a thin client system, a PC authentication device which authenticates a client is set in an office of the client. Data existing in a server is printed by using a printer provided in the vicinity of a client PC according to the following steps. (1) The PC authentication device performs authentication with the client PC and acquires an identifier IDa of the client PC. (2) The PC authentication device notifies the server of the identifier IDa of the client PC and an identifier IDb of the PC authentication device. (3) The server registers the printer provided in the office where the PC authentication device having the identifier IDb is set as a printer which can be used by the client PC having the identifier Ida. According to the above-described flow, when the client PC is coupled with the server, the printer can be used.
