Terminator code. This command prints dot graphics at 240 horizontal dot per inch by 180 vertical dpi.
The parameter values should be calculated as follows:
n
1
Remainder of the number of columns divided by 256.
n
2
Integer result of the previous division.
p
1
Sum of the values corresponding to the dots that should be printed in the first column of the
graphics pattern.
p
2
Sum of the values corresponding to the dots that should be printed in the second column of the
graphics pattern.

This command selects dot graphics in 8 or 24 needle configuration. h*256+l represents the number of data
+ l. The m parameter represents the dot graphics modes as shown in the following table:
m DENSITY NEEDLE FUNCTION
0 60 8 Same as ESC K (8 needles)
1 120 8 Same as ESC L (8 needles)
2 120 8 Same as ESC Y (8 needles)
3 240 8 Same as ESC Z (8 needles)
8 60 24 Same as ESC * (32)
9 120 24 Same as ESC * (33)
11 180 24 Same as ESC * (39)
12 360 24 Same as ESC * (40)

parameters are dot graphics data. If you select the 8 needle dot graphics mode, one
byte of data is needed for each column so that the formula h*256+l = number of columns + l is valid. If
you select the 24 needle dot graphics mode, three bytes of data is needed for each column so that the
formula h*256+l = number of columns *3−l is valid.
