I have a HP ScanJet 4300C, which I managed to use with (almost) no problem while running Knoppix.

The Windows driver for this scanner gives me the option of descreening scanned images, to eliminate that "mosaic" look you get when scanning, say, a magazine picture or a sports card. I scan lots of things like this for eBay selling, and would like to know if there's some sort of adjustment I'm simply overlooking.

Thanks in advance for any help!
