Hexadecimal dump
This feature isusefulfor programmers who are debugging printingprograms
and want to see the actual codes the printer is receiving. (Some computers
change the codes the programmer intended.)
In thismode, all data received will beprinted in a hexadecimal dump format,
rather than the control codes being acted on as command codes.
This mode is accessed with the following procedure:
1. While holding both the I
PAPER FEED 1and [ EJECT/pARK1buttons down,
turn power ON. A beep tone will be heard and the “Hd” message on the
display.
2. Begin printing. In place of the usual printout you will get a formatted
dump showing exactly what data theprinter receives. Each line presents
sixteen characters, their hexadecimal codes to the left and printable
characters printed on the right.
3. At the end of the hexadecimal dump, set the printer off-line with the
ON LINE
\
button. This is necessary to print the last line.
