I’m thinking about taking the leap but I need printer support to work.
In my experience printer support in Linux is generally pretty good. Even when it doesn’t “just work” you usually need only a simple profile file from the manufacturers website that you install.
In general drivers on Linux have been way less painful for me than on Windows; most importantly you don’t need an always-running application for every crappy piece of hardware.
But you still might want to check your printer manufacturer’s website and/or make one prototype Linux PC and try everything out.
With that being said be prepared for users complaining about some workflow changes (that will be bigger with a switch to something like LibreOffice from MSO) and blaming every issue of theirs on Linux and you.
