I have PS programs that are 13 MB in size.  They have no bitmaps, just 
180,000 gray-filled triangles.  Takes about 4-5 hours to print on a LaserWriter
Plus (mostly due to the 9600 baud serial line).  I assume that adding memory
would not make a difference in my case.  If I had a way to render the PostScript
into a bitmap and send that I would do it, since my calculations show a bitmap
for the whole page would be only about 1 MB, about 1/10 the size.
