[Description] Selects a bit image mode using m for the number of dots specifi ed by nL and nH, as fol-
lows:
m MODE
VERTICAL DIRECTION HORIZONTAL DIRECTION (*1)
N° dots DPI DPI N° of data (k)
0 8 dot single density 8 67 100 nL + nH × 256
1 8 dot double density 8 67 200 nL + nH × 256
32 24 dot single density 24 200 100 (nL + nH × 256) × 3
33 24 dot double density 24 200 200 (nL + nH × 256) × 3
[Notes] • The nL and nH commands indicate the number of dots of the bit image in the horizontal
direction. The number of dots is calculated using: nL + nH x 256.
• If the bit image data input exceeds the number of dots to be printed on a line, the excess
data is ignored.
• d indicates the bit image data. Set a corresponding bit to 1 to print a dot, or to 0 to not
print the dot.
• If the value of m is outside the specifi ed range, nL and data following it are processed
as normal data.
• If the width of the printing area set by $1D $4C and $1D $57 is less than the width re-
quired by the data set using $1B $2A, the excess data are ignored.
• To print the bit image use $0A, $0D, $1B $4A or $1B $64.
• After printing a bit image, the printer returns to normal data processing mode.
• This command is not affected by the emphasized, double-strike, underline (etc.) print
modes, except for the upside-down mode.
• The relationship between the image data and the dots to be printed is as follows:
