500 or so i’ve Had a black and white laser for ten years and would like to add colour and duplexhow many pages are you looking to do a month?

Recommend the HP Color Laserjet Pro MFP M281fdw A4 Colour Multifunction Laser Printer
Any of the Brother printers would be my choice. They are cheap to buy, 3rd-party toner is cheap as chips, and they are pretty reliable. We buy them for work as throw-away deskside printers with the idea that as soon as something, anything goes wrong with them we will just bin it and buy another. I've yet to bin a single one.......
