I poll printer queue on any change like JOB_CHANGE, and if I see that some job disappeared, I report to server that job has been printed or deleted, according to job last status.

Problem is that printer Lexmark X945e returned last job status only JOB_STATUS_RETAINED, but no JOB_STATUS_DELETED or JOB_STATUS_PRINTED.

What does that mean? Can I use retained status to say that job was printed?

  • Do you mean JOB_STATUS_RETAINED when you say RETAINED? – sashoalm Nov 11 '14 at 14:29
  • @DevOvercome set printer attribute PRINTER_ATTRIBUTE_KEEPPRINTEDJOBS to get JOB_STATUS_PRINTED but don t froget to remove job in spooler. – ceyun Jan 08 '19 at 12:34

In case you meant JOB_STATUS_RETAINED when you said RETAINED, I found this link in the documentation:

Windows Vista and later: Job has been retained in the print queue and cannot be deleted. This can be caused by the following: 1) The job was manually retained by a call to SetJob and the spooler is waiting for the job to be released. 2) The job has not finished printing and must finish printing before it can be automatically deleted. See SetJob for more information about print job commands.

From SetJob documentation:

JOB_CONTROL_RETAIN Windows Vista and later: Keep the job in the queue after it prints. JOB_CONTROL_RELEASE Windows Vista and later: Release the print job.

From the documentation, it seems that SetJob(JOB_CONTROL_RELEASE) could be used to release the job.
