I have a UFRII LT printer that is not working at all. I have added the latest drivers from Canon (just updated in December) and followed this tutorial. I had a VERY hard time getting this printer to work in Ubuntu, but after an hour or two I was running smoothly and never had another problem.
In OMV, for some reason, I cannot get the printer to print. It is detected by the server, it adds easily in the CUPS plugin or the CUPS admin UI, and is using the correct driver from Canon. When I try to print a test page, it just says "Processing" and never goes anywhere. I've reinstalled about 10 times now, trying every possible option as well as some of the other drivers for similar models, but no dice.
Any suggestions? These printers are notorious online for having poor Linux compatibility, but I figured since it worked with Ubuntu, it would probably work with Debian. Exact model is MF4350, but that shouldn't make much of a difference. I'm using driver version 3.40.
