Horizontal Format
Graphics data printed in horizontal format is comprised of a stream
of bytes from left to right across each dot row.
This chart shows that byte 1 (or character 1) in row 1 prints its six
bits from left to right in a single dot row. The next byte (byte 2) prints
its six bits, representing a character, in the same dot row across the
page.
