Divide the number of dots to be printed by 256. The interger answer is nH and the
remainder is nL. Therefore, the number of dots in the horizontal direction is calculated
by nL + 256 x nH.
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.
The bit-image modes selectable by m are as follows.
m
No. of Vertical Dots
Dot Density

Maximum number of dots
0 8 Single

1 8 Double

[Notes]
If the values of m and nH are out of the specified range, the following data is processed
as normal data.
After printing a bit image, the printer returns to normal data processing mode.
The relationship between the image data and the dots to be printed is as follows.

[Description]
Turns underline mode on or off,
When n = 0 or 48, underline mode is turned off.
When n = 1 or 49, underline mode is turned on.
[Notes]
Underlines can be printed for all characters, but not for the space set by HT.
This command and ESC ! turn underline mode on or off in the same way.
If n is out of the specified range, this command is ignored.
