These files are from the CD that came with the scanner. Should contain both USB and Parallel Port drivers. The drivers are installed during the installation of the Precision Scan Ver 3 software. Have not tested these drivers by themselves or with an older version of Scan software (Ver 1). The setup.exe file is not a valid Win32 program. (The Scan software is an approx 80Mb file.) You may have to order the CD from HP.
