5.3.7.1.2 B IT IMAGE GRAPHICS
ASCII
ESC * m n1 n2 data
Hexadecimal 1B 2A m n1 n2 data
Comments: The bit image graphics command formats and prints a bit image depending on m, n1, n2
and the data..
All graphics are single density: m = 0.
n1, and n2 specify the number of bytes sent (data).
n2 is the high order byte ( 0 ≤ n2 ≤ 1 ), n1 is the low order byte ( 0 ≤ n1 ≤ 255). The total
number of data bits to send is calculated by the formula n2 x 256 + n1. For 384 graphic
bytes, the maximum per line, then n2=1, n1=128. The data (d) is formatted as shown
below.
