m DPI Graphics ESC # m n1 n2 data
Selects eight wire graphics of density m as listed in the following table for n2 + (n1 x
256) columns of data.
m Density
90 90 dpi
100 100 dpi
135 135 dpi
150 150 dpi
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.
Example: The following escape sequence will print five bytes of graphics data at 150
dpi. The resulting figure will resemble a backslash character, "\".
Escape Sequence: ESC # 150 0 5 64 32 16 8 4
Hexadecimal: 1B 23 96 00 05 40 20 10 08 04
