Debug mode
After the self-test is printed, the printer system enters the debugging mode. In the debugging
mode, all the volume labels will be printed as machine code. The ASCII strings on the left are
the data received by the system. The data on the right are printed from the strings on the left, in
hexadecimal values. This function is provided for users or engineers to debug programs. You
only need to restart the printer to leave the debugging mode and return to the normal printing
mode.
