are u using default disk for drivers installation? it may have a problem that your drirs arent writen for the winXP, you might acn still use your printer anyway, but it wont show its original drivers.
you can check outt HP's web site, they may have re-developed drivres for XP, as I ave searched the drivrs, and couldnt find the drivers written for this printer in XP platform.
