Is there any support (native or through SANE), using any
GNU/Linux distro, for this type of scanner
Sorry ... you'll have to click the link; there's no support for inline images.
Here are some other examples:
Pentax DSmobile 600
IRIScan Express 2
RoadWarrior Sheet-fed Mobile Scanner
Xerox Travel Scanner 100
Plustex OpticSlim M12Plus
Genius Color Page SF600 (illustrated in link)
These models are much faster and therefore more convenient (they scan in a single-pass) than flat-bed scanners, for scanning receipts and other single-page documents. The above models are reasonably priced as well. But, their manufacturers list only drivers for the various MS Windows versions.
It could not be, could it, that an entire category of scanners could be unusable with GNU/Linux?
