PCL 5 and HP-GL/2 generally don't do 1200 DPI; there are exceptions
on high-end DesignJet plotters, but none of the PCL 6 capable printers
in my lab will do 1200 DPI in PCL 5 or HP-GL/2 mode.

Regardless, if you can get the kinks ironed out, this *will* help
for some pages - the key will be to know when it is better to just
rasterize the whole page since vector ops can be slow on the non-
PCL 6 devices.
