I purchased the Officejet last August and used in through December with a Dell with no problems whatsoever. When I bought an HP Slimline with Vista 64 the printer started spitting out a dozen pages with a few lines of garbage characters for each document including the Test Page, and did not completely print the documents. I spoke with three technicians who were all given remote access. We each spent about 3 hours per session. They were unable to make ANY progress in solving the problem. HP provided a VISTA 64 installation disk. It should not have done so. HP has taken no responsibility for releasing a product to market that is not ready for use but will not accept it back and will not give credit for the expensive paper weight that it has become. Moral of story: stick with Dell, don't buy anything from HP.
