LPR Failed to send print file command


Before I go to far ripping my hair out, I was wondering if anyone could advise the likely cause of the following error? LPR Failed to send print file command

We have several successful print jobs which processed today, however this one job is failing to print correctly. Thoughts? The printer logs do not receive this print job at all.

We have already:

  • Restarted the workflow service
  • Restarted the LPR client service
  • Restarted the printer and printer controller
  • Reviewed the printer logs (nothing reported)

Thanks in advance.

Hi @iwest,

Please check if the Weaver Engine log files does contain any detail information about the β€œLPR Failed to send print file command” error message. These log files are stored at the following location:


Please check if you are also getting an error by executing the Create Output Workflow plugin when you send the same job to a different printer queue.

Whilst the Weaver engine logs were not helpful, I expanded the investigation to other logs.
I was able to find related error messages here instead.


Reviewing the log files, the printer seems to be at fault. The output is processed and output creation completes.

To approach diagnosis, we have split the larger print job into two, both halves of the job appear to print fine. We’re now considering how to reduce the size of a single print job so they are handled by the printer.
