I Have had trouble with HP and XP since upgrading. Although they say it is xp compatable with driver, it is not. Will cause system to lock up and when I called HP they blamed XP. Bought a Epson and first time install without a hitch. Hope this helps and God bless you!

Ex Output:
Negative

Good quality overall. The braket for the stem didn't fit my application, so I improvised, and mounted it behind the seat over the rear fender and low. Holds stuff.
