yeah - I am thinking this is the issue...

Can I ask a really basic question, that may help me get my hands
around this stuff...On the windows side the application prints using
the ADOBE (or whatever) Driver and the vendor specific PPD file.  It
then gets sent to cups which then does what??  Does the CUPS server
process it again before sending to the printer (assuming the printer
is postscript capable)?

The reason I ask, was that I thought (for some reason) that the CUPS
processing made the windows client driver independent - but if the
windows client uses the PPD - then I am thinking that I was mistaken

Thanks for your input
