I'd like to hear comments about how Display Postscript is fast
enough to be used as a display system whereas Printer Postscript
seems to be the bottleneck on many laser printers. Is my
assumption about the cause of the bottleneck correct? What is
missing from Display Postscript that makes it unsuitable to also
be Printer Postscript? Does Display Postscript performance degrade
when complicated images are displayed the way Printer Postscript
does? What are the other differences that make the speed of
Display Postscript so much better?
