These are the drivers off for the HP Scanjet 3300c off the CD ROM that came from HP. I searched for 6 hours on the 'net for them and didn't find them. It works only for Windows 98 and the latest version of Windows 95 (OSR 2) because they are the only versions that have USB support. You will also need the PrecisionScan LT Software from HP which can be downloaded from their site. A link to this is posted by someone else on this site. Good luck.
