Postscript emulation

[pubpc1@library.ucla.edu]

How difficult would it be to write a printer driver that
contains a Postscript rasterizer?  The driver would have
to intercept Postscript output, convert it to a bitmap of
a certain resolution, and output it to a printer.  This
could give ImageWriters, DeskWriters, and every other
printer capability to print at their maximum resolution
even though they don't have Postscript built in.  Each
unique printer would need its own Postscript aware driver.

Macintosh computers have this type of driver available
commercially.  Although probably not feasable commercially
on the GS, is it technically feasable?
