Selects one of eight graphics modes depending on the value of n0
and prints g-pin bit-image graphics in this mode. The graphics
image is 9 dots high and nl + n2 x 256 dots wide. Maximum width
is 8 inches. Dots beyond the right margin are ignores. ml, m2, . . . are
byte pairs representing 9 vertical dots each. In the leftmost position,
the most significant bit of ml is the top dot; the least significant bit
of ml is the second dot from the bottom; the most significant bit of
m2 is the bottom dot; and the other bits of m2 are ignored. Other byte
pairs are similar. The number of data bytes must be 2 x (nl + n2 x
256). At the end of bit-image printing the printer returns automati-
cally to character mode.
