And no to Virtual PC too. http://www.aspdeveloper.net/Virtual_PC/rn-739-55577_Saving_legacy_scanner.aspx
To get an idea about how the HP 4200c differs from all other scanners read http://www.sane-project.org/sane-mfgs.html and find your HP 4200c. You discover the driver in SANE was created just for the 4200c and does not support other scanners.
There is no generic driver.
-> Solution. Connect it up to some supported machine, scan there and use a memory key or network to move the scans over.
Has anyone gotten the HP 4200c flatbed scanner to work on Win Vista? HP says they will not provide a driver update for Vista. I wonder if there is a generic driver out there. Thanks
