Open office is a dead project, avoid at all costs. LibreOffice or OnlyOffice are active.

Probably linux mint. Everything tends to work out of the box and function the way you'd expect. If you're used to windows then cinnamon will have a familiar feel to it. I like xfce myself, but I move things around to make it feel like windows 95.

Linux mint provides the best overall user experience including drivers support

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.

Please, don’t use Open Office. Dev essentially halted on it years ago when it was forked o LibreOffice. Use LibreOffice instead. The Open Office project seems to still exist to trick people into using old software.

I'd say keep it basic with Ubuntu. It's not exciting, but it 'just works' out of the box and there's TONs of support if you can't figure something out.

It needs testing to ensure you get what you need, but I found printer support worked better on Linux for my obscure printer. If you setup a CUPS server then distros will automatically find the networked printers. SUSE/OpenSUSE also has a very good GUI printer admin with lots of automatic setup and auto driver downloads...makes it so easy.

I'm loving KDE's Neon distro that's based off Ubuntu. I've not had to do much faffing around to get it the way I want it and anyone that has used Windows should be comfortable using it. KDE Plasma feels very polished and streamlined.

Debian is solid and will come ready with office and web apps. You might want to check out if drivers are available for your printers though. You can always try it out on a live USB.
