According to the bit image mode assigned in m, prints data in the bit image.
l The no. of dots printed is divided by 256, whose quotient is taken as n2 and residualas n1.
l The total no. of dots printed in the bit image is equal to n1 + (256 x n2).
l When bit image data have been input in excess of 1 dot/line (448 dots) position, the excess
data are discarded.
l In the bit image data (Dn), the bits subject to printing are taken as "1" and those not as "0".
l The bit image modes are shown as follows:
VERTICAL DIRECTION HORIZONTAL DIRECTION
m(Hex) MODE NO. OF DOTS DOT DENSITY DOT DENSITY MAX. NO OF DOTS
0 8-dot single density 8 67 DPI 101 DPI 288
1 8-dot double density 8 67 DPI 203 DPI 576
20 24-dot single density 24 203 DPI 101 DPI 288
21 24-dot double density 24 203 DPI 203 DPI 576
l When the value set in m (bit image mode) are out of conditions, the data following after n1 is
processed as printing data.
