Abstract: This invention aims at conducting a scheduling work of print processing efficiently. A device scheduler refers to print job composition information registered in step control information of the step “printer reservation” of other print job (other order) in a workflow information table, and a schedule information table. The device scheduler searches both other print jobs (proof print jobs and regular print jobs) that a to-be-registered proof print job having a processing time of the proof print job described above affects and other print jobs (proof print jobs and regular print jobs) that affect the to-be-registered proof print job. The device scheduler determines whether the to-be-registered proof print job can be registered in a schedule (there is no search result in Step 2017 described above). When the registration is not possible, the device scheduler informs an operator of the result that automatic scheduling is impossible.
