So it's failing for all systems, despite having been triggered by the
Windows 11 update?

Is it feasible to try to use it without Windows 11 just to see if the
problem re-appears?

Can any of the other systems be used as a printer server 24/7 (or at
least when needed) to avoid printing directly from Windows 11?

(I don't have any pointers, sorry, I'm just coming up with some
questions to try to understand the mystery.)

Another one: does the Windows 11 Canon driver have any configuration
options?
