Horizontal Format

Graphics data printed in horizontal format comprise a stream of bytes from left
to right across each dot row.
Table 11 shows that byte 1 (or character 1) in row 1 will print 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.

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
