Hi all,

I recently got a new computer (openSUSE 10.2, x86_64, fully patched) which 
does not have a parallel port. However I have an old HP Laserjet 4M (old, but 
works well) which only has a parallel port connection.  This is at home, and 
I have a small D-Link DI-704P router which has a built in parallel port for 
sharing a printer - exactly what I would like to do here.

After a rather frustrating bit of time I sort of have the printer working.  I 
set it up as a remote LPD server (router address 192.168.0.1) with 
queue "lp".  This "sort of" works in that the test pages (from CUPS and YaST) 
print just fine, but the document I wanted to print wouldn't.

By trial and error I discovered that some documents will print, however some 
won't.  For example, kwrite will print a text file (/etc/fstab for example) 
just fine, and postscript and pdf files generated (through CUPS) from this 
file using kwrite also print fine (from acrobat for example). However, 
openoffice writer with a simple text file will not print (the lights on the 
printer blink for a few seconds but then stop and no paper comes out).   
Similarly a pdf generated in openoffice writer from a simple text file does 
not print.  Other pdf files (generated in Kile for example) seem to print OK.

So, not all postscript of pdf files are created equally.  However, I know very 
little about the format of postscript and pdf files and how these differences 
could affect essentially just the data passing through the router. (These 
files print just fine with this printer on another machine with a parallel 
port so I know the printer works.) I've looked at the logs in the router and 
the only messages related to printing are pairs of messages like

Printing jobs started from <name of machine>
Printing job finished

with no indications of any errors.  I checked the D-Link web site and there 
are no firmware upgrade for this router, and all of the support seems to be 
windows based.

I've tried several different ppd files for this printer (though not all) and 
they each show the same behavior.  I'm not sure what else to try and am 
looking for some suggestions (wild guesses also accepted).

I hope someone here can shed some light on this for me.

(I could always get a pci card with a parallel port I suppose, so if I don't 
get this to work that is probably what I will do, but of course I would like 
to figure this out. )
