Just bought this printer. I have all minimum reqts on my Dell pc. While attempting to install get error "Device driver has not met the Microsoft Windows XP logo reqts." On phone with HP for 2 hours and they couldn't solve. Thought it was just a glitch with the printer and want me to take it back and get another. I wasn't impressed with their diagnostics (try loading, click thru error) and don't really want to go thru this again on what I suspect will be a problem on the next f4400 I get. Anyone know anything?
