I'm using Ubuntu 24.04.4 on x86_64 PC with Canon MF230. Printing a pdf file from Okular worked just fine last night, but stopped today. PC reboot and power cycling the printer didn't help. Here are the screenshots showing the print job permanently stuck on pending:
The scanning works just fine, but the printing doesn't. Any clues will be greatly appreciated.
Printing from another Ubuntu 24.04.4 PC goes into processing mode for a few seconds and stops in paused mode.
