[Description] Selects a bit-image mode using
m for the number of dots specified by
nL and nH, as follows:
• 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.
[Notes] • If the values of m is out of the specified range, nL 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):
➀
The width of the printing area is extended to the right to
accommodate the amount of data.
➁
If step
➀
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. This must be considered in calculating
the amount of data that can be printed in one line.
