Sow if > your scanner not have funny firmware it proberly runs on epson2 The 4990 model is listed with "complete" support both in the epson backend and the epson2 backend. This is somewhat strange as with a support status of "complete" this should never happen. :-( > (if it use > the ESC/I, but I think that both v700 and v750 use the ESC/I commands, but > don't blame me if I'm not right) commands, but .

Whenever I read something about scanner support I see "no documentation available" and "reverse engineering with USB traffic sniffing". > I don't know how much you can do, can you compile a packet your self ? - do > you programe/understand some c ? I can read C programs to get the most basic idea what it should do, but this is not nearly enough for driver development. :-( You offered a radically different view onto the support situation of the named epson devices (4990 / V700). So I'm again a bit more uncertain about purchasing one of these. But at the moment I'm lacking alternatives! > Best > > Claus Boje Best regards, Adolf Winterer
