While we don't maintain an official list of compatible printers, I've never seen many issues with standard, non multi-function, plain ol' Inkjet printers from HP and Epson.
The printer I used at home for the past few years was a Deskjet 952c, which is long out of production, but it worked flawlessly with our print server from both PC and Mac systems on the network. It failed mechanically though after several reliable years of service, and was replaced with a PhotoSmart 4580, which has wireless built into it, negating the need for using a print server anymore.
I apologize for not being able to narrow down the printer list, but stick to a norrmal inkjet printer that doesn't scan or fax, and you should be fine. Most printer companies do cover "print languages" in their spec sheets, if you're looking to make sure the printer you're browsing for supports PostScript.
