Obviously I disagree with your main point, but, considering I have been a Linux only user (in my personal life) for over a decade, it's only natural that I would consider it easy to use and intuitive, as such, I won't even try to argue against that assertion.

With that said, if you want to make a point against something just working, you may want to choose something other than printers as evidence of how bad Linux is. Printers are universally terrible on every OS.

Anecdotally, I have had far fewer issues with printers on Linux than I have had with printers on Windows. But, most of the "tech support" I do for printers is from people who are arguably tech illiterate and using Windows. So, I'd again consider that a wash that doesn't really add weight to either side of the argument.

tl;dr: printers are universally terrible and we should all stop using them anyway
