Debugging 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 in 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 turn off and
on the power again to leave the debugging mode and return to the normal printing
mode.
