This all-in-one web driver includes all of the same Windows software as the in-box CD with the following components removed to reduce download time: Memories Disk, Product Tour, and Share-to-Web.
Instructions for Installation
Download the web package to your desktop. If you have already installed the software for this device and you are either upgrading or re-installing you will need to disconnect the USB cable from your all-in-one, turn the device off, and then uninstall the software. The previous installation can be removed by running the Uninstall Software program via the START\Programs\Hewlett-Packard menu or via Add/Remove Programs in the Windows control panel. Please reboot your PC when prompted.
