Unable to use Brother printer after update to F35

jhaiduce · November 19, 2021, 9:25pm

I have a Brother printer, model MFC-L8850CDW. It worked well in Fedora 34 and earlier. Upon upgrading to Fedora 35 I can no longer send jobs to the printer (the built-in scanner still works though).

The CUPS web interface says “Unable to locate printer” in the job status when I try to print.

I tried re-installing the printer from the Gnome printer settings. The printer is listed when I click “Add Printer…” and restored to the printers list when I click “Add”. But when I try to print jobs I get a message that the printer is rejecting jobs. CUPS shows the same message in the printer settings.

The printer uses a proprietary driver which is distributed as an rpm from Brother. The driver version installed on the system was already the latest before the update to F35, and I verified that it was still installed after the update to F35.

Not sure if this is a problem with the printer driver, or with some component of Fedora. Can anyone suggest ways to diagnose?
