[Outline]

• This command specifies the bit image of the m-mode as to the number of dots specified with

 

 

nL and nH.

 

 

 

 

 

 

•nL and nH denote the number of horizontal dots of the bit image to be printed, resulting in [nL + nH ⋅ 256] dots.

•If the bit image data is input beyond the dot position printable in one line, the surplus data will be discarded.

•d denotes the bit image data. Set "1" in the corresponding bit when printing, and "0" when not printing.

•The following table lists the bit image mode selected with m.

[Caution]

• If a value of m or nH goes beyond the range, this command will be ignored, processing the

subsequent data as normal one.

•Normal data processing is restored after printing the bit image.

•The following page shows the relations between the bit image data and the dots printed.

•The double density bit image is invalidated in the page mode.
