I have imageCLASS MF4570dn
connected via USB.
I have cnrdrvcups-lb
installed. When I try to add printer (as mf4500 series) and print test page I see following:
1. Printer somehow displays "printing...", blinking green indicator and nothing more. No printing at all, printer doesn't try to do something with paper.
2. At the same time cnpkmoduleufr2r
process eats 100% CPU.
Once it was single beep from printer when I try to print test page.
P.S. Same with scanner capability for this device. Sane\Simple scan saw MFU but there were Device is busy
\Unknown error
when I tried to scan.

Canon also supports this driver on i686 and MIPS64 .
IF
you run archlinux (or something close to it) on such a processor
AND have a supported printer
AND are willing to help test necessary adjustments
THEN please send me an email.

The printers supported by this package are often networked.
problems can be in the cnrdrvcups-lb driver, but also with authentication over smb, vpn settings etc .
Troubleshooting those is often very hard.
Archlinux and derivatives are not supported by canon. Use whatever works for you, even if that means using canon drivers in a VM that runs a supported distro .
