  • Print system managing the security of a printer shared on a network
    Patent number: 6202092
    Abstract: Authority of each user to use a printer is set in a security data base with respect to the number of sheets to be printed, kinds of sheets, and special printing functions. A print request, including the number of sheets to be printed, the kinds of sheets, and whether special printing functions are to be used are sent to a security validating device, and the security validating device decides whether authorization to use the printer is to be granted based on the restrictions on the user maintained in the data base and the status of the user. If printing is authorized, after the printing is completed, an editing device updates information on the status of use in the security data base.
