[Description]
Selects a bit-image mode using
m
for the number of dots specified by
(
nL
+
nH
×
256), as follows:
•
d
indicates the bit image data.
[Notes]
■
If the value of
m
or
nH
is out of the range, this command is canceled, and the following
data is processed as normal data.
■
Data (
d
) specifies a bit printed to 1 and not printed to 0.
■
If the bit image data exceeds the number of dots to be printed on a line, the excess data is
ignored.
■
The bit-image is not affected by print mode (emphasized, double-strike, underline,
character size, white/black reverse printing, or 90° clockwise-rotated), except for upside-
down printing mode.
■
After printing a bit image, the printer processes normal data.
■
When printing multiple line bit images, selecting unidirectional printing mode with
ESC U
enables printing patterns in which the top and bottom parts are aligned vertically.
■
This command is used to print a picture or logo.
