This is the minimum driver required for basic WIA functionality. This driver enables scanning with the Windows Photo Gallery on Windows Vista or the Scanner and Camera Wizard on Windows XP. Scanning can also be done with a variety of 3rd party scanner enabled applications. You might find that some features are no longer available when using this basic driver. We are sorry to inform you that a full feature driver for Windows Vista or Windows XP Professional x64 Edition will not be available for your HP product in the future. You can upgrade to an HP product that is fully compatible with Windows Vista or Windows XP Professional x64 Edition if additional features are necessary.
