5 year or more year old used HP enterprise workgroup printer only or mopier with low page count are ideal for personal use. In general, the more expensive the initial purchase price of laser printers, the more repairable and durable and lower cost per page they are. (I worked in a large university department in the 00's where they had zillions of network enterprise HP printers of all sizes.)

I have an HP LaserJet Pro M402dw because I don't have a particular need for color.

Lots of great black and white options in laser printing. Even Laser LED printers (okidata, etc) are good bang for the buck.
