[Description]
Selects a bit-image mode using
m
for the number of dots specified by
nL
and
nH
, as follows:
•
m
specifies the print mode of the bit image
•
nL
and
nH
specify the number of dots of the bit image in the horizontal direction as (
nL
+
nH
× 256) dots
•
d
indicates the bit-image data
•
k
specifies the number of bit-image data
[Notes] ■
d
indicates the bit-image data. Set a corresponding bit to 1 to print a dot or to 0 not to print a dot.
■ If bit-image data and character data are printed on a line, the bottom of the bit image is aligned to the
baseline (the second dot from the bottom) of the built-in internal character.
■ If bit-image data input exceeds the number of dots to be printed on a line, the excess data and the number
of dots of the bit image in the horizontal direction which is specified by
nL
and
nH
, are discarded. Then the
printer performs the buffer-full process when the next data is input.
