(8) Specifying the bit Image (ESC * m n1 n2 D1 ~ Dn)
Code : [1B]h + [2A]h + m + n1 + n2 + Dn
* {m= Bit image mode (refer to the table below)}
{0 n1 FF}
{0 n2 02}
The data is described with the hexadecimal code.
Prints the data in the form of bit image in accodance with the bit image mode specified by "m".
The number of bit printed is divided by 256, and n2 and is assumed to be a quotient, and n1 to be the
remainder.
The total number of dots printed in the form of bit image is n1 + (256
When the bit image is entered beyond a 1 dot line (576 dots) position, the surplus data is discarded.
For the bit image data (Dn), the bit to be printed is set to "1" and that not to be printed to "0".
The following table shows the bit image mode.
m(Hex)
0 8-dot single density
1 8-dot double density
20 24-dot single density
21 24-dot double density
When the value set for "m (bit image mode)" dose not meet the condition, the data subsequent to n1 is
processed as printing data.
