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. After you make sure the printer is off, open the cover.
2. Hold down the
FEED
button while you turn on the printer.
3. Close the cover.
4. Run any software program that sends data to the printer. The
printer prints “Hexadecimal Dump” and then 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.
