Actually, it doesn't matter. Install an operating system to any computer (from OrangePi Zero to a CRAY-1, doesn't matter), install a "virtual" PDF printer and share from the network. It'll appear as a printer. It'll print to a folder local to that machine, not yours. It's again the same thing (this is the magic of the network, actually).
IIRC from administering my parents' Windows PC, the OS now has Print to PDF capability built-in, but IDK whether that virtual printer is installed with Office, but it's out of the box.
