Used to print user--generated bit map graphics across the
width of the print head. After receipt of this command, the
printer will dump the binary data supplied directly to the
print head. As customary with bit map data, a "1" bit indi-
cates a dot is on, "0" bit indicates the dot is off.
Graphics printed in this manner must be the exact width of
the head in bits. Bit 7 of the first byte of data received will
print at the left--most dot on the head as you view the head
with the paper feeding away from you.
