[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.
*1: The total number of horizontal dots in the page mode differs depending on the printing area
secured with ESC W and printing direction specified with ESC T.
