Function
Prints the next (

1*256 + n2) dotlines as bit-mapped
graphics.
n1n2
form a 16-bit binary number set, the most
significant byte first. Used to print user-generated bitmap
graphics across the width of the printhead. After receipt of this
command, the printer dumps the binary data directly to the
printhead. As customary with bitmap data, a
1
bit indicates a
dot is on,
0
bit indicates the dot is off. Graphics printed using
this command must be the exact width of the head in bits. Bit
7
of the first byte of data received prints at the left-most dot
on the head as you view the printhead with the paper feeding
away from you. The printer remains in
bit-mapped graphics mode until the total amount of bytes
necessary to fill
n1n2
lines of print are received by the printer.
Use the following table for guidelines when adding a bit-
mapped graphic.
