Problems solved by technology

However, during the execution of the second image task, depending on whether the first and second image tasks perform post-processing after the image is formed, there are cases where priority output processing is not performed. In this case, such as when urgent The priority cannot be changed when outputting, so there is room for further improvement

Abstract

An image forming apparatus which includes: a job storage unit for storing a plurality of print jobs; an image forming unit for executing the print jobs stored in the job storage unit; and a job managing unit for managing an execution order of the print jobs performed by the image forming unit. The job managing unit includes: priority job managing portion which, during execution of a specific print job carried out according to an execution order set in advance, manages the image forming unit to suspend the specific print job and preferentially to execute another print job; and job continuation judging portion which, when completing a priority print job that is executed by the priority job managing portion, judges whether or not to continue execution of the specific print job based on a job execution state of the specific print job that is being executed when starting the priority print job.

Description

technical field [0001] The present invention relates to an image forming apparatus including: a job storage unit storing a plurality of printing jobs; an image forming unit executing the printing jobs stored in the job storage unit; and printing performed by the image forming unit A task management unit that manages the execution order of tasks; wherein, the task management unit has a priority task management unit that interrupts the execution of a specific printing job in accordance with a preset execution order. Printing tasks to give priority to other printing tasks. Background technique [0002] In an image forming apparatus connected to a public line or a network to receive print jobs from a plurality of terminals and store the print jobs, the print jobs are usually executed in a predetermined order of execution, for example, in the order of reception. In addition, devices with a queue-cutting printing function are also very common, so that when there is an urgent prin...
