[Description]
Selects bit-image mode using
m for the number of dots specified by (n

,x256).
This command is used to print a predefined picture or logo.
The modes selectable by
m are follows;

[Notes]
The
n
L
and
n
H
indicate the number of dots of the bit image in the
horizontal direction.
The number of dots is calculated by
n
L
+
n
H
x 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 of 1 to print a dot or to 0 to not print a dot.
If the value of m is out of the specified range,
n
L
and data following are
processed as normal data.
If the width of the printing area set by
“
GS L
”
and
“
GS W
”
less than
the width required by the data sent with the
“
ESC ＊
”
command the
following will be performed on the line in question (but the printing cannot
exceed the maximum printable area) :
① The width of the printing area is extended to the right to accommodate
the amount of data.
② If step ① does not provide sufficient width for the data, the left margin
is reduced to accommodate the data.

For each bit of data in single-density mode, the printer prints two dots :
for each bit of data in double-density mode, the printer prints one dot.
