Postscript
I seem to remember that the different things you could do with postscript
and display postscript were both very very CPU intensive. You needed to
have the full page in memory to manipulate the bitmap. Most laser printers
had so many milliseconds for the page commands to be interpreted, rasterized
and produced before timeout. We used Xerox 2700 and 3700's and found that
the with the timeout we ended up with 2 pages each with 1/2 of the image.
All of the connections were either parallel or serial and that was also a
limitation.

We tried early non-storage Tektronix terminals did graphics list processing.
Lots of primitives, simple fonts.

Later ones the memory prices were cheap enough to have an entire page.
