Creating the Character Data
Each dot column is sent to the printer as three bytes of data. To get the values of
this data, convert the binary values to hexadecimal values.
The ampersand figure shows the hexadecimal value for each byte in each
column of the character. For example, the last byte of column one is binary 1100
0000 or 192, xC0.
Initializing the Download Area
Use the following command to initialize the download area:
First byte of data (most significant byte) Top 8 print wires
Second byte of data Middle 8 print wires
Third byte of data (least significant byte) Bottom 8 print wires
<x
1B3D - download command prefix - initialize download area
0000 - byte count (low byte first) - 0
