2.2.5 Bit Image Commands
ESC * m n1 n2 [ d ] k
[Function] Specifying the bit image mode
[Code] <1B>H<2A>H<m>H<n1><n2>[<d>]k
[Range] m = 0, 1, 32, 33
0≤n1≤255
0≤n2≤2
0≤d≤255
k = n1 + 256 x n2 (m = 0, 1)
k = (n1 + 256 x n2) x 3 (m = 32, 33)
[Outline] • According to the number of dots specified in “n1”, “n2”, specify the bit image of mode
“m”.
• The number of dots printed is divided by 256, whose quotient is taken as n2 and
residual as “n1”. The total number of dots printed in the horizontal direction is equal
to n1 + (256 x n2).
• When bit image data have been input in excess of dot positions that can be printed
on one line, the excess data are discarded.
• ”d” is bit image data. Bits to be printed are specified as “1” and those not as “0”.
• The bit image modes specified by “m” are shown as follows:
Vertical Direction Horizontal Direction
m Mode
No. of Dots Dot Density
Dot
Density
Max.
No. of Dots
0 8-dots single density 8 67 DPI 101 DPI 288
1 8-dots double density 8 67 DPI 203 DPI 576
32 24-dots single density 24 203 DPI 101 DPI 288
33 24-dots double density 24 203 DPI 203 DPI 576
[Caution] • When the value of “m” is out of the above range, the data following after “n1” is
processed as normal printing data.
• After completion of bit image printing, the printer returns to normal data processing
mode.
