I’d avoid inkjets and go straight to laser, possibly this one by HP:

mainly as I’ve been using a cheap HP laser for years, sadly not colour or networked, but it’s never played up once, and has had precisely one new cartridge despite printing literally thousands of pages.
OTOH I’ve owned a Lexmark Inkjet for years, and its been a monumental pain in the arse every time I attempt to use it. The scanner no longer works. Printing happens in a variety of unpredictable sizes, if at all. Photos come out with varying density despite never changing any settings. Cartridges appear to last about 20 photo prints (half of which will be double size printed straight onto the rubber roller).
I could recommend anything but a lexmark, as mine has been utter shite.
