2. Turn on the printer, while holding down the FEED button.
3. Close the cover, then the printer enters the hexadecimal dump mode.
4. Run any software program that sends data to the printer. The printer will print 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 corresponds to the
codes.
