n1, n2 are two-bits of hexadecimal number, n1 is the low byte, n2 is high
byte, denote the width of printing graphics set by ESC commanded, the
number of dots is within the maximum line-width dots number of the
printer.
When m=0, select normal print, maximum print dots number is 210.
When m=1, select half dot print, maximum print dots number is 420.
At this moment the adjacent two dots of each dot-line can’t be 1.
Definition for d is:
Bit-map Graphics Data
Notice: When in bi-directional print mode, the print speed is faster
than that in single directional mode, but may appear the phenomenon
that it is not neat correctly from head to foot , this is caused by its
own principle of the printer’s structure, belonging to normal
phenomenon.
Notice:
1. Please select single directional print mode with ESC U command
before printing the bit-map graphics.
2. Allow printing bit-map graphics and characters in the same line.
