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.
If the width set for the printing area is less than the minimum width of the bit-image data to be printed,
the printer performs buffer full printing for the current print line; then the remaining data is printed from
the beginning of the next line.
[Example] The relationship between the image data and the dots to be printed is as follows:
