[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.
