Printer used to work, but abruptly stopped

Hi,

I have a Canon ImageClass MF3010. A week ago it was working great, but this morning it stopped working.

When sending it a print job it does nothing but I get a notification that the job is complete. This is described in the Arch Linux Wiki under CUPS, but the proposed solution is a driver upgrade, but the printer was working last week, so the driver is up to date.

So far I tried:

  1. Rebooting the computer and printer.
  2. Uninstalling and reinstalling the printer.
  3. Tested the scanner (to ensure the USB plug works.)
  4. Ran the command lpinfo -vwhich lists the printer and doesn’t show anything weird.

How strange - I have exactly the same problem with a canon MF4100.

The printer works fine on macbook (of course) and worked fine on manjaro until a couple of days ago (not exactly sure since the printer isn’t used that much).

CUPS reports no errors and says the job is completed.

A real WTF :slight_smile:

Here is the output of lpoptions -p Canon_MF4100_Series_ Does anything look weird?

In case anyone is still watching, the problem is a ghostscript “upgrade”

ghostscript - 9.53.2-1 does not work
ghostscript - 9.53.3-2 does work and is available at:

spoke a little too soon … local printing with canon now works but I get the same original symptoms (no printing, no errors) with network printing …
