Descender Mode ON prints:

Half-Tone
Lines, boxes, and characters are printed in solid black, but they can also be
printed in patterns of dots. These patterns are called half-tones. Many half
tone patterns are available, such as vertical, horizontal, and diagonal lines, as
well as many other designs.
The selected pattern becomes the default pattern as long as the Graphics
Mode is enabled. Once Graphics Mode is disabled using the command ^PN^-
, the dot pattern defaults to the pattern corresponding to 04 hex.
See Appendix D, “Patterns” on page 273 for all available half-tone patterns.
The following command is used to turn on the Half-Tone Mode as well as to
select a half-tone pattern:
Command ^KLxx<data>
Arguments
^KL Turns ON the Hfl-Tone Mode.
xx Specifies the half-tone pattern, where xx equals
any hex number between 00 and FF.
<data> Data to be printed using the selected pattern.
Example: The Graphics Pass ^M0303000^KL02DOT PATTERN^- prints:
^KL Turns ON the Half-Tone Mode.
02 Selects the half-tone pattern corresponding to 02.
DOT PATTERN
Data to be printed using the selected pattern.
