Corrupted outgoing faxes (linejumps)

I Have a strange problem that caused a lot of frustration to my. As usual I
reviewed the docs, the mailinglist-archives and the webpages but to no
avial :-(
The problem:
I generate a PS-File by printing a Word 7.0 (Win95) document to a Apple
Laserwriter (which actually does not exist :) ) and redirect the
priontoutput to a file (maybe fax.ps)
I then 'faxspool <number> fax.ps' and the magic happens. GS complains
abount long lines in the file (think itīs GS ?!) but promisses to have that
fixed up. File has been spooled successfully.
[BTW there is an output of gs during spooling (only with Win95-originated
ps-files) -> %%Page1%% or similar - is that normal? ]
I run faxrunq and the g3-file gets faxed out.
The received fax on the remote station is corrupted. At two or three
positions, the fax breaks and continous without any space inbetween with
the faximage a few lines before...uhh..you canīt see what i mean - right?
In other words: line1,line 2 and line 3 are printed, the suddenly line 2
appears again, then line 3 and so on. Like a little backwardsjump in the
datastream.
I fiddled around with flowcontrol, switchboard, speeds all night to no
avial. always the same results.
I recently faxed a generic "linux-world" PS-File (intro.ps of the
sendmail-docu) and that fax has not been corrupted!
(only minor errors: The top-pixelline of bold type went away...but still
readable)
So I thounght I must be obviously something wrong with the
Win95-PS-production....
meeeeeppp...wrong!
I looked at that g3-file that goes out corrupted with "g3view" and saw a
nice g3-sheet with no linejumps on it!
So....what? I have no further idea.
pbm2g3 is from the mgetty-set - so thats not the point.
The stuff concerned:
Linux 2.0.30 (S.u.S.E.-Dist.)
Modem GVC 28800 Fax class2
remote FAX Philips HFC21 thermofax
mgetty+sendfax 1.1.6 (same result with 0.99)
Ghostscript 4.01
PS-producer: Win95-Printerdriver (Apple Laserwriter and HP 4M PS) with
ps-output to file
pfffft....thats it.
I would be very thankful for any good idea or advice. Pleae eMail ME, Iīm
not to sure now if I successfully joined the list :)
So, thanks in advance
Christian
