If systemd had broken yet-another-thing, many more users here would be posting about broken cups, I on the other hand am using my printer as we speak (work) , my wife has to use it all day, every day.
I du 3-4 times a day, unless on holiday, then, it's up to the cat, that lazy no good moth%^ &^@#!* !, so it ends up done when I get home
I can't remember the last time I had an issue with cups, hmm, kanotix, knoppix days, many years ago
You would also be seeing this (failing) at #debian-systemd and I haven't unless I missed something
