Printer is not accepting jobs in RHEL

Issue

• We're trying to print to a printer, but we're getting the following message in the CUPS Error Log:

  D [25/Jan/2021:10:51:19 -0500] Create-Job server-error-not-accepting-jobs: Destination "printer-Xerox6510dn" is not accepting jobs.
  

• The output of lpstat -t for a print queue shows that the queue is enabled, but not accepting jobs:

  $ lpstat -t | grep PR3415
  device for PR3415: socket://10.1.2.3
  PR3415 not accepting requests since Mon Feb  8 15:06:24 2021 -
  printer PR3415 is idle.  enabled since Mon Feb  8 15:06:24 2021
  

• We configured the printer, but queuing is disabled state:

  # lpc status PR3415
  PR3415:
          printer is on device 'socket' speed -1
          queuing is disabled
          printing is enabled
          no entries
