Looking at Arch, at a guess, either a general upgrade of cups2 and
its packages in June, or else an upgrade of cups-filters in August.

But, I don't have a working printer so I cannot rule out that it
might be in lualatex - I see Arch last upgraded that in May.  Of
ocurse, it depends when printing last worked for you, and also how
up to date your system (or Endeavour OS) was at that time.

I was going to suggest turning on debug logging in cups, but I tried
searching for the error message and found a report from today for
Arch:

 - fix for that is to downgrade cairo!
