Hexadecimal Dumping Mode

In hexadecimal dumping mode, data from the host computer is printed in hexadecimal numbers
and characters. By comparing the print outs and the program, you can check whether or not data
is being sent to the printer correctly.
• When there are no characters that correspond to the print data, " . " is printed.
• If you press the Feed button when there is less than one line of print data, one line is
printed.
• During hexadecimal dumping mode, applications that check the printer status may not
operate correctly. The printer only returns the status for the "Real-time transmission sta-
tus" command.
Follow the steps below.

mal numbers and ASCII characters.
