2.6 You want to check a software program
To use the hexadecimal dump feature, follow these steps:
1) After you make sure that the printer is off, open the rear cover of the printer.
2) Hold down the FEED button while you turn on the printer.
3) Close the rear cover.
4) Run any software program that sends data to the printer. The printer prints "Hexadecimal dump" and then all
the codes are received in a two column format. The first column contains the hexadecimal codes and the
second column gives the ASCII characters that correspond to the codes.
5) When the printing finishes, turn off the printer.
This feature allows experienced users to see exactly what data is coming to the printer.
This can be useful in finding software problems. When you turn on the hexadecimal dump function,
the printer prints all commands and other data in hexadecimal format along with a guide section to help
you find specific commands.
