As the Windows printing system is designed to pass
*print ready* data to the printer, you *must*, for
PostScript printers, use the printer specific PPD
on the Windows side.

"Generic" PPDs usually restrict the generated PostScript
to the smallest subset thought to be common to all
printers - especially assuming the printer is only
a black and white device.
