Like my big Ricoh network printer. Print and scan over the LAN from XP, W7 and W10. Prints ok from Linux but won't scan. Not tried the FAX on any OS but there is a FAX package for Windows.
Now, unlike yer Linux fanatic, I'm not simply going to go without or turn down a free printer simply because I can't use it fully from Linux, I'll use whatever OS gives me the best range of solutions that supports *my needs*.
However, in contrast to the vast majority of ordinary computer users who have never even heard of Linux, let alone used it, at least I try to keep my hand in in the hope that it will one day be capable of being a real alternative desktop OS for me. And it *has* come a long way over the years, from my first experiments using SLS 0.9 that came on 3 x 1.44M floppies to the mainstream offerings like Ubuntu and Mint of today.
