Creating the Character Data
Each dot-column is sent to the printer as three bytes of data. To get the value for
the first byte of data, convert the binary values of the bottom eight print wires to
hexadecimal. The most significant bit of each byte is the top dot. The least
significant bit of each byte is the bottom dot.
The figure on page 141 shows the value for each byte in each column of the
character. For example, the last byte of column two is binary 0001 0000 or 10.
The character data is shown in the following example.
