1.6.2 Hexadecimal Dump Function
To put the printer in hex. dump mode, power it on while pressing both the LOAD/EJECT and LINE
FEED/FORM FEED buttons. In hex. dump mode, the printer prints out the hexadecimal representation
of the input data, along with the corresponding ASCII characters. This function is valuable for checking
the data the printer has received from the host. If input data is a control code rather than a character
code, a period
(.)
is printed in the ASCII column.
