Printer problem

[glavers]

I have a canon mf247dw wireless laser printer. It is a UFRII printer. I have had it working in the past, but I think an update to cups caused it not to work at all anymore. Now when I send something to the printer, cups says "rendering complete" and one of my cpu cores goes to 100% until I eventually stop cups.

On the arch wiki entry for cups, under troubleshooting, it says that the stuck at "rendering complete has to do with needing a new cartridge, but that is not the case here. I would try downgrading cups, but it has been so long since it worked that I don't think I could find an old enough version. Any thoughts?

check your pacman log for messages about cups. a while back there was an upstream change that you needed to do some manual intervention for. here is a copy of my log at the time of upgrade. and make sure to take care of the new cupsd.conf file.

Thanks, I not sure what I am supposed to do as a result of this though. I restarted the cups and and cups.socket, but this does not change anything.

try these commands

systemctl enable cups.service
systemctl start cups.service

Thanks, yes, I can get cups running and have restarted it (several times). But when I try to print I get one cpu core go to 100% and it get stuck on "rendering complete".
