Eight-Bit Graphics
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 eight
bits from left to right in a single dot row. The next byte (byte 2) prints
its eight bits, representing a character, in the same dot row across
the page.
