2.6 Bit-Image Commands
The printer supports the following bit-image command:
Command
ESC *
Print bit image vertical mode
ESC X
Print bit image horizon mode
ESC f
Print downloaded bit image
ESC *
m nL nH d1 dk
[Name] Print bit-image vertical mode
[Format] ASCII ESC * m nL nH d1…dk
HEX 1B 2A m nL nH d1…dk
Decimal 27 42 m nL nH d1…d
[Range] m = 0,1,32,33
0 ≤_nL ≤ 255
0 ≤ nH ≤ 3
0 ≤ d ≤ 255
[Description] Select a bit-image mode using m for the number of dots specified by nL and
nH, as follows:
Vertical Direction Horizontal Direction m mode
Number of Dots Dot Density Dot Density Number of Data
0 8 dot single 8 60 DPI 90 DPI
nL+nH
x256
1 8 dot double 8 60 DPI 180 DPI
nL+nH
x256
32 24 dot single 24 180DPI 90 DPI
(nL+nHx256)x
3
33 24 dot double 24 180 DPI 180 DPI
(nL+n
Hx256
)x3
[Note]
1
If the values of m are out of the specified range, nL and data following are
processed as 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.
4
If the bit-image data input exceeds the number of dots to be printed on a line, the
excess data is ignored.
