I'm looking for a good business all-in-one printer that can do A3, color, scan and copy. I'll use it intermittently in the beginning, but possibly a lot more a few months down the line. Ideally it can do WiFi as well. I'll be printing B&W mostly, but need the ability to print A4 and A3 color charts and brochures.
Have no preference for laser or inkjet, whatever works without complaints - and the cheapest possible over the long run.
Any suggestions on a good workhorse printer?
