Claim:
A printing control device having a function that adds a visible security image automatically unless an instruction for canceling an addition of the security image is issued, comprising: an input operation unit by which an operation of the instruction for canceling the addition of the security image is performed; a print data generation unit that generates print data to which the security image has been added when the instruction for canceling the addition of the security image has not been performed by the input operation unit, and that generates print data to which the security image has not been added when the instruction for canceling the addition of the security image has been performed by the input operation unit; a printing control unit which outputs the print data to the printing device; a print log acquisition unit that acquires print log information when the print data to which the security image has not been added has been generated by the print data generation unit; a print information storage unit that stores the print log information and the print data when the print data to which the security image has not been added has been generated by the print data generation unit; and a cancellation notification control unit that sends a cancellation notification message to a computer used by a system administrator when the security image has not been added to the print data and does not send the cancellation notification message to the computer when the security image has been added to the print data, wherein the printing device carries out printing processing without putting the security image when the security image has not been added to the print data output by the printing control unit and carries out print processing with putting the security image when the security image has been added to the print data output by the printing control unit.
