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 two-sixteenth character shows the hexadecimal value for each byte in each
column of the character. For example, the last byte of column one is binary 0000
1010 or 10, x0A. The character data is shown in the example below.
Initializing the Download Data
Use the following command to initialize the download area:
First byte of data (most significant byte) Top 8 print wires
Second byte of data Center 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
