To reduce the labor and time of a user.

A multifunction peripheral (MFP) control system 100 includes an MFP 1 and a controller 3. The MFP 1 includes: a job reception section 10a for receiving job data on a print job; and a transmission source specification section 10c for specifying the transmission source of the job data and transmitting transmission source information indicating the specified transmission source to the controller 3. The controller 3 includes: a storage device 32 for previously storing the transmission sources which are permitted to use a print job performance function in the MFP 1; and an authentication processing section 31b for performing job authentication processing on the basis of the transmission source information received from the MFP 1. The authentication processing section 31b does not give permission to the MFP 1 to perform the job when the transmission source indicated by the transmission source information received from the MFP 1 is not stored in the storage device 32, and gives permission to the MFP 1 to perform the print job when the transmission source indicated by the transmission source information is stored in the storage device 32.
