	However, The HP_PaintJet's BLUE is the bluest blue I've ever seen
for an ink-jet printer.  As you probably know there is a trade off in 
getting the colors 'correct' since inks have to be in the YMCB form
and monitors are in the RGB form.  I think that HP did a good job,
their red seems pretty good to me.

	BTW, the Xerox_4020's dot density is the same in both the X and Y
dimension.  It is 120x120 dpi.  If one turns on the 'special mode' then
it is still 120x120 dpi BUT the printer outputs every line twice, moving
the paper up 1/240th of an inch and spraying the dots 1/240th of an
inch to the right.  This (sort of) gives an effective resolution of
240x240 (but not really).  It actually ends up producing much more
vibrant colors although large areas of solid mixed colors
(full red=magenta+cyan, green=yellow+cyan, and blue=magenta+cyan) tend to
oversaturate the paper.  It is quite an interesting effect.

	The HP_PaintJet's resolution is 180x180 dpi.  Both are fine printers.
