NOTE: Horizontal movement of the FormsPro 4000 print head is measured in
intervals of 1/720 of an inch. Every supported graphics density above is an integral
multiple of this resolution. For example, at 60 dpi, dots may be printed every 12/720
of an inch.
Example: The following escape sequence will print four bytes of graphics data at 72
x 72 dpi. The resulting figure will resemble a square, since the horizontal and vertical
density are the same. If some other density is chosen, the figure will resemble a
rectangle.
