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 No. of dots (vertical) No. of dots (horizontal) No. of dots/line
0 8-dot single-density 8 (68 DPI) 0–288 (101 DPI) 8 x 288
1 8-dot double-density 8 (68 DPI) 0–576 (203 DPI) 8 x 576
32 24-dot single-density 24 (203 DPI) 0–288 (101 DPI) 24 x 288
33 24-dot double-density 24 (203 DPI) 0–576 (203 DPI) 24 x 576
Value of n:
Value of n (8-dot single-density mode) Value of n (24-dot single-density mode) Value of d
n1 + (256 x n2) 3 x [n1 + (256 x n2)] Number of bytes of data*
*Printed left to right (8-dot mode); printed down then across (24-dot mode)
Formulas
8-dot single-density= n1 + (256 X n2)
24-dot single-density= 3 X [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.
See the illustration for graphic representations of the bit image below.
