PROBLEM TO BE SOLVED: To prevent the lowering of the throughput of job execution as a whole caused by emission recovery processing when a plurality of printing jobs are continuously executed. SOLUTION: After printing jobs are executed, a timer is respectively started with respect to a time A and a time B and it is monitored whether these times are elapsed at the start times of the respective jobs. When either one of the times A, B is elapsed, recovery processing is performed before the printing jobs are executed. By this constitution, the lowering of throughput caused by recovery processing can be prevented as compared with a case performing recovery processing at every printing job. |
