PROBLEM TO BE SOLVED: To prevent an illegal copy printing of contents data. SOLUTION: Printing job data to be transmitted from a contents server 44 to a printer 38 contain contents data CD and printer specification information PI, with which a printer identifier for specifying a printer capable of printing these contents data CD has been enciphered. In the printer 36, which receives the printing job data, the printer specification information PI contained in the printing job data are read out and deciphered and it is judged whether the printer identifier contained therein is matched with its own printer identifier or not. Only when both the printer identifiers mutually match, the printing of the printing job data is executed. |
