NOTE: Horizontal movement of the FormsPro 4000 print head is measured in
intervals of 1/720 of an inch. The supported graphics densities above may not be an
integral multiple of this resolution. For example, at 150 dpi, dots may be printed
every 4.8/720 of an inch. The printer is not really capable of printing dots every
4.8/720 of an inch. It will print the dots as accurately as possible, with some at 4/720
of an inch and some at 5/720 of an inch. The overall average will be 4.8/720 of an
inch.
