Function Prints the next (n1*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.
