[Range]
0≤xH≤255, where 1≤(xL+xH×256)≤48
0≤yL≤255

[Description]
Selects raster bit-image mode. The value of m selects the mode, as
follows:

xL, xH, select the number of data bytes (xL+xH×256) in the
horizontal direction for the bit image.
yL, yH, select the number of data bits (yL+yH×256) in the vertical
direction for the bit image.
[Note]
In standard mode, this command is effective only when there is no
data in the print buffer.
This command is not affected by print modes (character size,
emphasized, double-strike, upside-down, underline, white/black
reverse printing, etc.) for raster bit image.
λ
λ
Data outside the printing area is read in and discarded on a
dot-by-dot basis.
The position at which subsequent characters are to be printed for
raster bit image is specified by HT (Horizontal Tab), ESC $ (Set
absolute print position), and GS L (Set left margin). If the position at
which subsequent characters are to be printed is a multiple of 8.
The ESC a (Select justification) setting is also effective on raster bit
images.
λ
λ
d indicates the bit-image data. Setting a bit to 1 print a dot and
setting it to 0 does not print a dot.

When xL+xH×256=64
