Digital BW, The Print

Thanks Roy, that's very useful.

I certainly have ghostscript installed, it comes with Redhat 9.
rpm -q ghostscript returns "ghostscript-7-05.32.1", to be exact.

If I understand you, we'd like to see /usr/bin/ghostscript being
invoked (with some set of options, I'm sure) during CUPS
processing in place of imagetoraster. 

Hmmmm... How to change this.... Wild guess, I grepped for 
imagetoraster in /etc/cups and I see that there are many 
references to imagetoraster in /etc/cups/mime.convs for 
starters... what does the image/jpeg entry in that file 
look like on the Mac?
