This is available (and meaningful) only on the ImageWriter.  The pixel array
that the Imagewriter lays down is not the same aspect ratio as the screen;
the distance between dots is less horizontally than vertically.  Thus, a
direct printout of screen dots, or font dots, will make an image proportion-
ally narrower than the screen would indicate.  Normally this is not a real
problem as the amount of difference is very small.  However, it is particu-
larly bad if you are printing out things that are noticable, such as circles
which print out as vertical ellipses.

The "Tall Adjusted" option allows you to specify a correction factor, so that
the ImageWriter driver maintains the correct visual aspect ratio.
