[Code] <1B>H<2A>H<m><n1><n2> [<d>] k
[Range] m= 0, 1, 32, 33
0 n1 255
0 n2 3
0 d 255
k = n1 + 256 × n2 (m = 0, 1)
k = (n1+ 256 × n2) × 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 × 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:
mMode Vertical Direction Horizontal Direction
No. of Dots Dot Density Dot Density Max. No. of Dots
0 8-dots single density 8 67 DPI 101 DPI n1 + n2 × 256
1 8-dots double density 8 67 DPI 203 DPI n1 + n2 × 256
32 24-dots single density 24 203 DPI 101 DPI (n1+n2 × 256) × 3
33 24-dots double density 24 203 DPI 203 DPI (n1+n2 × 256) × 3
[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.
