HEX Dump Mode allows you to print the contents of the receive buffer in a hexadecimal format. This feature
allows the data stream to be examined for errors and troubleshooting.
After selecting the HEX Dump Mode in Operation Setting Mode, restart the printer (refer to Section 3.5

data continuously.
To exit the HEX Dump Mode, restart the printer by turning off the printer and then on again.
