PROBLEM TO BE SOLVED: To provide a printing controller capable of efficient interruption processing by measuring the performance of a printing job as strictly as possible. SOLUTION: On the basis of printing job data, a data size per page is calculated concerning preceding and following printing jobs (S11), information on a total page number is acquired concerning the preceding and following printing jobs (S12), and information on printing time until the occurrence of interruption processing in the proceding printing job is acquired (S13). Then, remaining estimated printing time D1 concerning the preceding printing job and estimated printing time D2 concerning the following printing job are calculated (S14). On the basis of the result, the estimated printing time D1 is compared with D2 (S15) and interruption processing is performed (S16). When interruption processing is performed, in a step S17, an interrupt history adding means 49 adds an interrupt history to the preceding printing job. |
