I've tried searching both on HP's site and Apple's but they are very vague about older HP wireless printers. The only guaranteed to work right now is the E-Print from HP. I have an "old" if you call 2 years old HP PSC 7250 (PSC 7280). It's not one of the cheapies. It cost me $300 when it came out. Fantastic wireless all in one printer. I'm a techie and upgrade almost all things electronics. But printers usually last me 5+ years. So is my current HP PSC 7250/7280 compatible?
