Maybe, sometimes. Twain has a optional protocol that can be used to do<br>
what you suggest. Problem is it is optional, and wasn't even in the spec<br>
until not too long ago. Hence most scanners don't support it, and less of<br>
the low end cheep ones. (read the very expensive ones are likely to<br>
support it, the ones you can accually walk into a store and buy probably<br>
don't - but all generalzations are false)<br>
<p>
Assuming the optional interface was implimented, the rest is a matter of<br>
programing. I don't think anyone has done enough work to make that<br>
possibal, but someone did suggest they were working one winSane, which<br>
would probably containe many of the parts. (not the part of turning twain<br>
into Sane, but the rest perhaps if the netbackend worked) <br>
