Possibly. But if so, I would expect this to be
a configurable item on the printer setup. I find
it hard to believe it is a PostScript thing. How
else would "scalable pixels" be implemented except
as polygons? 

But we are clearly out of my depth with regard
to exactly how PostScript printers work. :-)
