It’s worth mentioning that Arch wiki is the best place to go to solve that.
I’ve had a brother WiFi printer on the recent past and managed to get it going by… reading carefully the CUPS instructions on Arch wiki.
A month ago, my non-geek uncle had a similar difficulty with his wireless printer. I again got it going by pointing out where to look and what instructions to follow.
So, yes, printer problems on Arch stations are a real thing.
