Beware of advertised resolutions. Most of them are obtained by
_interpolating_ lower resolution images. You must look for _physical_
resolution instead. I've recently (1 month ago) bought a Genius
ColorPage-CS scanner, by KYE Corp., Taiwan. It advertises 4800 dpi, but
the _real_ physical one is 300 x 600 dpi. The driver software does its
magic. In Linux, you could easily use the Gimp or ImageMagick
to get the same effect. I have just finished my driver for the Genius,
after looking around for a "ready to run" unsuccessfully.
