Get it, Steve: "resolution" (really dot density) is a linear measure.  It's
the number of dots you get along a line of specific length.  400 dpi is a
33% increase over 300 dpi.

If you want to talk about the data volume for a given area, that's a 78%
increase from 90000 dots/square inch to 160000 dots/square inch.  But that
is neither resolution nor dot density, now is it?

Why hell, if you stacked the printed sheets one inch high and figure each
sheet is 1/100th inch thick, you could figure out the cubic data volume...
