Problems solved by technology

If the printer controller is restored at this time, some jobs will be unable to restore the normal job list due to the last abnormal exit, and these unrecoverable jobs may be discarded by the controller
Once the above situation occurs, the user needs to resubmit the job to the printer controller, and the user's time may be wasted due to the large number of jobs that cannot quickly determine the wrong job

Embodiment Construction

[0023] The core idea of ​​the present invention is: during the job processing process of the printer controller, back up the job attribute information and job list; when the job attribute information and job list change, update the backup. When the printer controller is restarted, the job list and job information in the job list can be restored from backup. In this way, even if an abnormal exit occurs during the processing of the job by the printer controller, the job list and the jobs in the job list can be restored normally, which enhances the stability of the printer controller and saves the processing time for the error job , improving printing efficiency.

[0024] The present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings. In the existing printer controller, there are generally three job queues, the first queue is a queue waiting for RIP processing, the second queue is a queue waiting for printing after RIP ...

Abstract

The invention discloses a job processing method for a printer controller and the printer controller, and belongs to the technical field of printing control. If the conventional printer controller is abnormal during job processing, the processed job information can be damaged and cannot be normally restored. During job processing of the printer controller, the method comprises the following steps of: snapshotting job attribute information and a job list and recording the job attribute information and the job list into a job attribute information snapshot file and a job list snapshot file respectively; updating the job attribute information snapshot file and the job list snapshot file when the job attribute information and the job list change; and reading the job attribute information snapshot file and the job list snapshot file before the printer controller is quitted last time when the printer controller is quitted and then restarted so as to restore the job list and a job in the job list.

Description

technical field [0001] The invention belongs to the technical field of printing control, and in particular relates to a job processing method of a printer controller and the printer controller. Background technique [0002] The printer controller generally refers to a file to be printed as a job. For the printer controller, its job processing status generally includes three statuses: waiting for RIP processing, waiting for printing after RIP processing is completed, and printing completion. Corresponding to different states of jobs, the printer controller generally has different job queues. Each job queue may contain hundreds or even thousands of job files, and as the job processing status changes, the job queue where the job is located will also change accordingly. When a large batch of jobs is output, if the controller is abnormal during job processing, or the computer system crashes inexplicably, the attribute information of the job being processed will be destroyed due...
