A project to get the HP scanjet 4600/4670 see-through scanner works under linux. There is no release yet, but the code is available through svn. Actually, the backend is unable to scan anything, but the HP4670 is well recognized by Sane/XSane
geniusvp2 is a SANE (http://www.sane-project.org/) backend for the GeniusŽ ColorPage-Vivid Pro II flatbed scanner. Currently, only the parallel port version is supported.
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.
