Selects a bit-image mode using m for the number of dots specified by n
follows:

• m specifies the print mode of the bit-image.
• n

+ n
• d indicates the bit-image data.
• k specifies the number of the bit-image data.
[Description] • d indicates the bit-image data. Set a corresponding bit to 1 to print a dot or to 0 not to
print a dot.
• If bit-image data and character data are printed on a line, the bottom of the bit-image is
aligned to the baseline (the second dot from the bottom) of the built-in internal
character.
• If bit-image data input exceeds the number of dots to be printed on a line, the excess
data and the number of dots of the bit-image in the horizontal direction which is
specified by n
process when the next data is input.
• If an adjacent dot is specified for the bit-image in double-density mode ( m = 17), the
right side of the adjacent dot is not printed.
• This command is not affected by print modes (double width or underline).
• After finishing processing the bit-image, the printer returns to normal data processing
mode. The next print starting position is located at the next dot of the last bit-image
data.
• "Dot density in the vertical direction" indicates the dot density in the paper feeding
direction, and "Dot density in the horizontal direction" indicates the direction
perpendicular to the paper feeding direction.
• The bit-image data is developed, based on the current print position.
