... or you could try to get the TWAIN driver running under WINE. Open source<br>
|
||
emulators (WINE, dosemu, ...) are a great reverse engineering tool, because<br>
|
||
decent operating systems can control almost anything going on inside the<br>
|
||
system/computer hardware. So WINE has some code that actually does the<br>
|
||
printer port emulation. At least it should.<br>
|
||
<p>
|
||
By the way: is their scanner driven by a SCSI-over-parallel protocol (which<br>
|
||
means that there is some SCSI driver installed by the Umax software) or is<br>
|
||
it some fully proprietary protocol? If it's SCSI then you can cut a few<br>
|
||
corners.<br>
|
||

<RANT><br>
|
||
It's very tiring always nag the large companies into releasing the specs.<br>
|
||
Especially Taiwanese/Japanese/Korean companies usually don't document<br>
|
||
anything. It's a shame, because they should do whatever it needs to sell<br>
|
||
more scanners. Linux is a small, but quickly growing market for their<br>
|
||
cheap rubbish. The Linux developers even write the drivers themselves.<br>
|
||
No other driver developers are that cheap. Probably they don't want to have<br>
|
||
anything on paper, because then everyone could see how badly<br>
|
||
designed/bug-ridden their stuff is and would laugh at them.<br>
