Linux/Samba would be fine for storing files from paperless office, and while you can use Samba for printing, I prefer CUPS. I definitely would not install MAS onto a Samba share, though. That's just asking for trouble. I run a linux (Centos 5) server at home for the phone system, file sharing, and printing, and I love it. We use Windows and Linux (ubuntu) on our personal PCs, and we have no difficulty using the shared printer or the file server.
