Hi again,
<BR>
I just discovered another problem.
<BR>
Again I thought that it might be a bug in my frontend,
<BR>
but the other frontends show the same behavior.
<BR>
I'm using Sane1.0.2 with the plustek backend 0.36-18 and
<BR>
a Opticpro 600P scanner on SuSE Linux 6.4.
<BR>
The parallel port mode is set to EPP (in the BIOS).
<BR>
<P>I tried to scan with a printer (HP DeskJet 500 C) connected
<BR>
to the scanner. Everything seems to work fine, preview scanning
<BR>
with 50 dpi is pretty fast.
<BR>
<P>Now I removed the printer, only the scanner is connected to the
<BR>
parallel port.
<BR>
The result seems rather weird: scanning with the same settings now is
<BR>
about three times slower :-(
<BR>
<P>I have no idea how to solve this. Might this be a problem with the
<BR>
backend, or maybe with the hardware?
<BR>
Can anyone tell me how I can figure this out?
<BR>
<P>Thanks a lot
<BR>
Michael
