Humm. I've never noticed that PS output wasn't
of acceptable quality. I've never had any difficulty
either producing a PostScript file (although I don't
think it is possible to do this *without* using the
printer dialog) or directly on a PostScript printer.
You have to be sure to set the VECTOR keyword. About
the only thing I have noticed is that some of the lines
are awfully thin. I usually jack the THICK keyword
up a bit if I'm producing PostScript line plots.

Doesn't this work, too:

newView = oldView

I've never tried it. But I can't believe it wouldn't
work just that wonderfully. :-)

Cheers,
