Divide the number of dots to be printed by 256. The integer
answer is n2 and the remainder is n1.
Therefore, the number of dots in the horizontal direction is cal-
culated as: .n1 + 256 x n2.
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 bit to 1 to
print a dot, otherwise set it to 0.
The bit image modes selectable by m are as follows:
Horizontal Direction
Horizontally
Dot Density
Adjacent Dots
Single density
Double density Prohibited
