  Could you clarify your explanation, what exactly constitutes the "Winxx 
PostScript driver" and the "NT4 kernel mode driver ".

  I have installed the drivers that come with the installation CDs for our 
different printers and put them into samba. They each produce a different 
selection of files of course. My only reason for making the windows users send 
their files via our samba/cups server is so that all outputs have a consistent 
banner, and we can do accounting etc. Otherwise they could all connect directly. 
The other advantage is that I install the driver files once and don't need to 
remember where i left the CD next time I need to install a windows machine!

p.s. sorry for the delay sending this, got distracted!
