<p>An authentication processing unit (113) performs an authentication process of determining whether printing of a printing job is allowed. A job control unit (112) executes the printing of the printing job when an authentication is obtained with the authentication processing unit (113) determining that the printing of the printing job is allowed. A faint-background generating unit (114) appends, upon the job control unit executing the printing of the printing job, information on the authentication to the printing job as faint-background data including a copy-control pattern that appears on a copy of a document.</p> |
