• Divide the number of dots to be printed by 256. The integer
answer is n2
number of dots in the horizontal direction is calculated as:
n1+256Xn2.
• If the. bit image data input exceeds the number of dots to
be printed on a line, the excess data is ignored.
• "d' indicates the bit image data- Set a corresponding
to 1 to print a dot, otherwise set it to 0.
• The bit image modes selectable by m are as follows:
m Number of Dots Dot Density
Vertical
in
Direction
0 8
• If m is out of range, the data following n1 (n1 is included)
N o t e s
is processed as normal data.
• After printing a bit image, the printer returns to normal data
processing mode.
• The relationship between the image data and dots to be
printed is as follows.
• Double-density bit image is disabled in Page Mode.
