[Name] Select bit-image mode.
[Format] ASCII ESC * m nL nH d1…dk
HEX 1B 2A m nL nH d1…dk
Decimal 27 42 m nL nH d1…dk
[Range] m = 0,1,32,33
0 ≤ nL ≤ 255
0 ≤ nH ≤ 3
0 ≤ d ≤ 255
[Description] Selects a bit-image mode using m for the number of dots specified by nL and nH, as
follows:
[Notes] 1) If the values of m is out of the specified range, nL and data following are
processed an normal data.
2) The nL and nH indicate the number of dots of the bit image in the horizontal
direction.
3) The number of dots is calculated by nL + nH x 256.
