[Description] Selects a bit-image mode m for the number of dots specified by
n
L
and
n
H
, as follows:
ù
The nL and nH indicate the number of dots of the bit image in the horizontal direction.
The number of dots is calculated by the formula
n
L
+
n
H

256.
ù
If the bit-image data input exceeds the number of dots to be printed on a line, the
excess data is ignored.
ù
d
indicates the bit-image data. Set a corresponding bit to 1 to print a dot or to 0 to not
print a dot.
ù
Bit image modes which can be selected by m are shown in the table below.

printing direction specified by
ESC W

ESC T
.
[Notes]
ù
If
m
and
n
H
is out of the specified range, the data following
n
L
is processed as normal
data.
ù
After the bit image is printed, the printer returns to the normal data processing routine.
ù
The relationship between bit image data and dots to be printed is given on the next
page.
ù
In page mode, double density bit image data is not available.
