Bit Image (BI) Graphics Mode Commands
BI
US * +nH +nL +data
1F 2A +nH +nL +data
256*nH +nL defines how many bytes of bit image data will follow. The data is received sequentially with
the first byte representing the first 8 dot positions at the top left side of the bit image with bit 7 being to
the left and bit 0 being to the right as printed.
XMOVE
US x +nH +nL
1F 78 +nH +nL
The horizontal print position is set to (256*nH + nL) * 8 dots from the left margin.
If there is a lot of white space on the current dot line, the XMOVE command can cause the print
location pointer to be moved resulting in less data required to define a dot line of bit image data to be
printed. Anytime there is more than 4 bytes of white space (32 dots) the XMOVE command will result
in less data being sent to the printer. Another BI command can follow the XMOVE command until a
YMOVE signifies the end of the current dot line.
YMOVE
US y +nH +nL
1F 79 +nH +nL
Causes paper to feed 256*nH + nL dot lines. This is also the BI line terminator and print command.
