I only have limited experience on that topic, but when I had to set up my printer, I found the arch wiki very helpful: https://wiki.archlinux.org/title/CUPS
Packages name might not match, but general info should be good for any distro.

When choosing a bug, if you start with one that is possible to reproduce, it might help following the instructions to reproduce it while debugging the app and observe what happens. This can be a way to start understanding how it all runs. Bugs without context or hard to reproduce are usually more complicated and you might need a better knowledge of the code to have an idea of where to look.
