Prints bit-image graphics at 60 dots per inch if n0 = 0 or 120 dots per
inch if n0 = 1. 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
ignored. 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 auto-
matically to character mode.
