I think that what he wants is to be able to connect his scanner to his<br>
|
|
Linux box, run saned on that, and have a parallel port driver running on a<br>
|
|
windows box that feeds parallel commands sent by whatever TWAIN driver<br>
|
|
came with the scanner, over to the saned which works in a pass-through<br>
|
|
mode, sending everything straight to the scanner.<br>
