[Outline]
• According to the number of dots specified in “n1”, “n2”, specify the bit image of mode
“m”.
• The number of dots printed is divided by 256, whose quotient is taken as “n2” and
residual as “n1”. The total number of dots printed in the horizontal direction is equal
to “n1 + (256
n2)”.
・
• When bit image data have been input in excess of dot positions that can be printed on
one line, the excess data are discarded.
•”d” is bit image data. Bits to be printed are specified as “1” and those not as “0”.
• The bit image modes specified by “m” are shown as follows:

[Caution]
• When the value of “m” is out of the above range, the data following after “n1” is
processed as normal printing data.
• After completion of bit image printing, the printer returns to normal data processing
mode.
