After many years working from home, best advice I can give is to just buy both a decent HP B/W laser printer and whatever all in one inkjet/scanner floats your boat. I'm partial to Epson for inkjet.

I always try to keep a spare laser cartridge on hand, but when they start to fade, a couple shakes and back in they go. I've gone weeks or months after the first indication of low toner.

Not so much for inkjets or color laser. When one color goes, they stop working. I think there's a Brother model that will print black only but never been a fan.
