This driver works for the 12p scanner with the following OS's Win 95b, Win 98, Win 98SE, Win ME, Win 2000, Win 2000 Pro, Win NT. I have used this driver with all the above OS's. I HAVE NOT tried this driver with Win XP.
Depending on the program you use with your scanner, you will have to choose from a list of twain compliant drivers. In some programs, this is done by choosing Acquire -> Select Source -> Scantak
Other programs may automatically detect this driver.
To use simply download the file then double click to install the driver.
