More Information
Summary:Content data (CD) and printer specifying information (PI) generated by encrypting a printer identifier to specify a printer capable of printing this content data (CD) are included in print job data to be transmitted from a content server to a printer. The printer which has received the print job data reads and decrypts the printer specifying information (PI) included in the print job data and judges whether the printer identifier included therein coincides with its own printer identifier or not. Only when both printer identifiers coincide, print of the print job data is executed. Hence, unjust copy print of content data can be prevented.
