Print requests issued by an interpretation section 13 are stored in an execution or wait queue of a storage section 21 by way of a print request receiving section 22. The print requests stored in the execution queue are input to an engine control section 15. When a report of completion of printing is issued by the engine control section 15, the print requests for which printing has been performed are deleted from the execution queue. In a case where collation printing is specified for the print requests, the print requests for which printing has been performed are transferred from the execution queue to the collation queue and stored therein. Every time one copy of the print job is completed, the print requests stored in the collation queue are again transferred to the execution queue. collation printing can be embodied by transfer of the print requests between the execution queue and the collation queue. <IMAGE> |
