While I haven't looked, good luck with HP. They were known for abandoning whole product lines when Vista came out.
I have to second the fact that HP is lower than low. They abandoned the 2800 and 13x19 printing with vista and for that i would not buy another printer with the HP logo on it if it was the last inkjet made. Regards
Hook it up and see if windows 7 has a driver for it via windows update. It might say the driver that it tried to put in in invalid. Just open up the box and have it check update for the driver. I've did this with a couple of driver issues and worked everytime for me. Nothing to loose.
