An image formation device stores therein print data targeted for secure printing received through a network. When a user is authenticated by a user authentication part, the image formation device reads the print data targeted for secure printing to execute a print job. The image formation device includes a job management part for managing the stored print data targeted for secure printing. When a print job is not executed at a point in time after the elapse of a predetermined period of time after the receipt of the print data targeted for secure printing, the job management part encrypts the print data using a certain encryption key, and transmits the encrypted print data to an intended device connected to the network. Namely, when a printout of the print data targeted for secure printing received through the network is not obtained at a point in time after the elapse of a predetermined period of time, the print data is transmitted to another device connected to the network with the security of the print data maintained. As a result, a printout of the print data is obtained by another image formation device.
