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 appears to have added i686 , ARM Aarch64 and MIPS64 processor support since Version 5.30 .
A quick peek indicates that the PKGBUILD will need adjustments to work on those other architectures.
If you do run archlinux (or something close to it) on such a processor, have a supported printer and are willing to help test the adjustments, send me an email.

On some systems printing fails while a component of this driver consumes 100% CPU . SmashedSqwurl figured out this appears to be related to differences between archlinux jbigkit and debian jbigkit.
A workaround is to install https://aur.archlinux.org/packages/libjbig-shared/ .

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 .

Main difference between 3.70 and 5.x versions :
3.70 has 64-bit & 32-bit code and needs to be built as a multilib application. Also it includes proprietary binaries from canon.
5.x is pure 64-bit and more parts of it are opensource.

People coming from cndrvcups-lb / cndrvcups-common-lb or cndrvcups-lb-bin :
You will have to start afresh.
html documentation from canon is in /usr/share/doc/cnrdrvcups-lb
