To realize protection (extension of life) and power saving of a hard disk device incorporated in a job process apparatus, both with a high level of achievement.

The individual of plural job process devices (printers 102, 103) transmits information (cumulative time ta) related to the number of power-on or power-off of a hard disk device to a server 104. The server 104 retains the information (cumulative time ta) related to the number of power-on or power-off of the hard disk device, the information received from the individual of the plural job process devices. Further, upon receiving print data from a PC 101 (S712), the server 104 determines a job process device for executing the job from among the plural job process devices (S714, S715) on the basis of the information (cumulative time ta) related to the number of power-on or power-off of the hard disk device, and transmits the job to the determined job process device (S717).
