Digital BW, The Print

Hello,
I bought IJC/OPM and installed the 1.1.0.8 release for windows xp to
print with my 4800. 

The big problem is that I am unable to print a file (tif format) or
the targets in OPM on this printer.

What occurs when i launch a print : the green LED on the 4800 is
blinking but it's the only thing I can see, nothing else occurs. Epson
remote panel shows the jobs send to the 4800 : all my tests with OPM
are logged but :
- the job has no name 
- the host has also no name
- there is a start printing date but no end (00/00/00 00.00.00)
- the width and height of paper is 0 mm.

So, the printer receive the printing job but it seems that it doesn't
understand it???

I tried to print targets on my epson 1290, all functions correctly.

I've checked that I have the latest version of quictime installed
(whitch is used to handle file transformation).

Bowhaus only said to me to check if I had selected "Epson 4800" in the
combo box!

Does somebody have advices or ideas to help me to solve this problem? 

Thank you
Christophe
