To enter hexadecimal dump mode, turn on the printer while pressing both the LOAD/EJECT and the
LINE FEED/FORM FEED buttons. In hexadecimal dump mode, the printer prints the hexadecimal
representation of the input data along with the corresponding ASCII characters. This function is useful
for checking the data the printer receives from the host. If input data is a control code instead of a
character code, a period (.) is printed in the ASCII
column,
