To turn off data dump mode, press the
PAUSE
button to stop
printing and then turn off the printer.
By reading the characters printed in the text field on the right side of
the printout or the printout of hex codes, you can check which codes
are being sent to the printer.
In the text field, characters appear as their true ASCII characters if
they are printable. Nonprintable codes, such as control codes, are
represented by dots.
