Do "Xerox publishing workstations" qualify as high end systems?

That URL I mentioned earlier
        < http://www.dungeon.com/~poota/lpbook/00-toc.html >

has this to say about PostScript's origins:

        "Interpress is a page description language, developed at Xerox
         by people who later left to form Adobe.  Interpress was primarily
         developed to communicate complex documents quickly and efficiently
         between Xerox publishing workstations and Xerox production printers
         via Xerox Ethernet networks...."

FWIW.
