What about me Mr. H and Mr. P?

I have an HP Photosmart 7550 printer, I also have Windows XP Pro x64 Edition. HP decided that there was no compelling reason to make a driver for this combination. Luckily, they were kind enough to point me in the right direction. To get your HP Deskjet, Officejet, PSC, and Photosmart printers working in x64 you definately want to check out this page: http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c00364537 For the HP Photosmart 7550 check out this page specifically: http://h10025.www1.hp.com/ewfrf/wc/genericDocument?docname=c00365046&dlc=en&lc=en&cc=us If either of these links go dead just head over to the HP website and type c00364537 in the search area at the bottom.
