This is a driver for the Artec AS6E parallel port scanner. It now can be run through a SANE interface, or as a stand-alone program. Version 0.4 scans pretty well in all modes, and at all hardware resolutions. It works in EPP, PS/2, and SPP modes.
The homepage says it all : free software for cheap hardware. I got myself a cheap dexxa flatbed scanner many years ago. It *almost* worked well on windows (with alternate drivers), but when I switched to Linux, that was another story. But now, with this driver, I have a fully functioning cheap flatbed scanner (it's even working better than the windows driver : no crashes anymore).
