Lexmark 249X, 248X manual 132, Initializing the Download Data

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.

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

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.
