Hexadecimal Dump
Press the PAUSE button while turning on the printer to put the printer in hexadecimal dump mode. In this
mode, received data is printed out in hexadecimal format, along with the corresponding ASCII characters.
This function is useful to check received data from the host. If a received code is not a printable ASCll character,
the printer prints a period (.) in the ASCII column.
