127, Creating the Character Data | Lexmark 248X, 249X specification

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	Middle 8 print wires

Third byte of data (least significant byte)	Bottom 8 print wires

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.
