Hexadecimal Dump
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 hex dump function, the printer
prints all commands and other data in hexadecimal format along
with a guide section to help you find specific commands.
To use the hex dump feature, follow these steps:
1. Make sure that the printer is off.
2. Open the cover.
3. Hold down the PAPER FEED button while you turn on the
printer by pressing the POWER button.
4. Close the cover. The printer prints “Hexadecimal Dump”.
5. Run any software program that sends data to the printer. All
the codes it receives 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.
