Hello  Gerhard

Sorry for my thoughtlessness! My RH distribution has SANE 1.0.3 but I've
tried to use the version 0.42 of the driver. Of course it won't work. But
I upgraded my SANE to the version to 1.0.8, recomplied and reinstalled the 
driver again. Then it works! So I can say that under RedHat 7.1 the 
Plustek scanner driver of version 0.42 for SANE 1.0.8 is OK. I made
several scannings with xscanimage. I used it in binary and grayscale modes
(600 dpi). The obtained page images were perfect. 
 The only problem is the operation in the color with the maximal
resolution (1200 dpi). I get a only nose in the image instead of any
page images but I think it is because of the SANE and not the driver.
 Anyway, I have a question concerning with pl.o. At the moment I use the
driver that way the pl.o is unloaded. Has the problem arisen the
interference between pt_drv.o and pl.o fixed in the latest version of the
driver, i.e., can I have the two modules loaded at the same time?

Besten Dank!

I've forgotten your scanner type... It might be the problem with the ASIC.
Former ASICS like the 96001 or 96003 used in Devices like OP4830, 9630 or
9636P are not able to buffer data and so it happens that they loose data
execpt the driver behaves no very cooperative to the system and stops every
other activity (like the ones under Windoze)...
If you have a device like 9636T, PT12 or so, the problem should not exist
or I have a problem within the driver...

What's pl.o? Never heard of it. You might enlighten me there ;-)

I have  OpticPro P12 scanner. Should it work?

Sorry for my second thoughtlessness! It's not pl.o but lp.o, of course.

Yes it should! I'll check this

Well, it has bee reported, that there are problems while the lp.o is loaded,
but in general it should work...
You might get problems while scanning and printing at the same time...
