Hello,<br>
<p>
there seems to be a serious lack of parallel port scanner support<br>
because<br>
there is no protocoll information avaiable for most parallel scanners.<br>
I have got such a prarallel port scanner myself (Primax Colorado Direct)<br>
and<br>
want to use it under linux.<br>
<p>
my questions:<br>
<p>
Is it possible to monitor the parallel port with a second computer to<br>
obtain information about the protocoll?<br>
<p>
I attached a second computer to the pass-through parallel port<br>
of the scanner.<br>
<p>
[ Sniffer] &lt;----[Scanner]&lt;----&gt;[Win]<br>
<p>
While scanning under Win95 with one computer, the other was<br>
able to get "some" data form the parallel port. I am really not an<br>
expert in hardware. So i dont know whether this data ist usefull<br>
or not. The transfer is in EPP mode. Could this be a problem?<br>
<p>
Marco<br>
