If you want a PostScript rip that runs on your Sun, you could try
NeWSprint (a Sun product).  If your printer speaks "laerjet" it should
run right out of the box, but if PRESCRIBE is more efficient for your
printer, you might want to code your own handler (probably no more
than a few hours work).

First, though, you might want to try to determine what is causing it
to be slow.  (If it's the rasterizing, NeWSprint is pretty speedy and
will probably help.)  I suspect, however, that some of the problem is
data transmission time between the machine and the printer.  The base
output from GO-Script (like NeWSprint and most other PostScript rips)
is raster, so for an 8.25" x 10.5" mono image you have to push about a
megabyte of data down to the printer.  Across a centronics connection
you can push bits quite fast if both sides of the interface support
(and are configured for) high data rates, so if your connection is
centronics you might check it out.

If your connection is a 19.2KB/sec serial line, however, it's going to
take about a minute per page to transfer the data:

   (1000KB / (19.2KB/sec)) == 52 sec

at 9600 baud it will take 2 minutes, etc.


Hope that helps.
