[Description] Selects a bit-image mode using
m
for the number of dots specified by
nL
and
nH
, as follows:
The number of dots in the horizontal direction depends on the
printing area and the printing direction specified by
ESC W
and
ESC
T
.
[Notes] • The
nL
and
nH
indicate the number of dots of the bit image in the
horizontal direction. The number of dots is calculated by
nL
+
nH
✕
256.
• If the bit-image data input exceeds the number of dots to be
printed on a line, the excess data is ignored.
•
d
indicates the bit-image data. Set a corresponding bit to 1 to print
a dot or to 0 to not print a dot.
• If the values of
m
and
nH
are out of the specified range, the
following data is processed as normal data.
• After printing a bit image, the printer returns to normal data
processing mode.
• In page mode, double density bit image data is not available.
• The relationship between the image data and the dots to be
printed is shown on the next page.
