[Description]

Selects a bit-image mode using m for the number of dots specified

 

by nL and nH

 

 

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.

[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.
