ABSTRACT:
In a printer control device, the number of printing sheets required for processing printing requests are detected, and when it is determined that the required number of printing sheets of a printing request is larger than a predetermined value, the order for printing is changed such that the printing request is processed later. Therefore, the problem is eliminated wherein a relatively short printing request is not processed for an extremely long period of time.
