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.

Vertical Format

In vertical format, each byte (or character) occupies six dot rows of
one column. Each character is one dot wide and six dots high. The
next character (byte 2) is printed beside the first, moving from left to
right across the page.
