Select bit image mode

ASCII
ESC * m n1 n2 d1 ... dn
Hexadecimal
1B 2A m n1 n2 d1 ... dn
Decimal 27 42 m n1 n2 d1 ... dn
Value of m:
Value of m Mode
0 8-dot single-density
1 8-dot double-density
32 24-dot single-density
33 24-dot double-density
49 Line Graphics
Value of n:
Value of n (8-dot single/Line Graphics)
n1 + (256 x n2)
*Printed left to right (8-dot mode); printed down then across (24-dot mode), bit gets printed to 1 and not printed to 0
Formulas
8-dot single-density= n1 + (256 X n2)
24-dot single-density= 3 X [n1+ (256 X n2)]
Line Graphics= n1 + (256 X n2)
Sets the print resolution and enters one line of graphics data into the print buffer. Excess data is accepted but ignored. Any
print command is required to print the data, after which the printer returns to normal processing mode.
The bit image is not affected by emphasize, double-strike, underline, character size, reverse printing, or 90 rotation, but is
affected by upside-down printing mode.
In page mode, a starting position of upper right or lower left results in rotated bit-image data printing.
See the illustration for graphic representations of the bit image below.
