I checked and it does appear debian patches jbigkit heavily [1][2].
If I understand you correctly, the problem is that UFR2 is hardcoded to use a library that's present in debian jbigkit but not in archlinux jbigkit ?
The contents of cnrdrvcups-common-5.20/cnjbig/cnjbig.c do reference libjbig.so.0 .
Wonder if redHat / fedora use the same patches as debian.
I'll consider adding jbigkit and your libjbig-shared packges as optional dependencies, but do have some comments about the new package and will post them there.

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
