[Description]
Select a bit-image mode using m for the number of dots specified by nL and nH,
as follows:

[Notes]
If the values of m is out of the specified range, nL and data following are processed as normal
data.
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.
After printing a bit image, the printer returns to normal data processing mode.
This command is not affected by print modes (emphasized, double-strike, underline, character
size or white/black reverse printing), except upside-down printing mode.
The relationship between the image data and the dots to be printed is as follows:
When 8-dot bit image is selected:
