Starting Hexadecimal Dumping Mode
In the hexadecimal dumping mode, the printer prints the data transmitted from a host device in
hexadecimal numbers and their corresponding characters. It enables you to check if data is transmitted to
the printer correctly.
Follow the procedures below.
1
Open the roll paper cover.
2
While pressing the Feed button in the printer, turn on the printer.
3
Close the roll paper cover.
The printer starts printing data received from then on in hexadecimal numbers and their corresponding ASCII
characters.
Example of printing in hexadecimal dumping mode
• If there is no character corresponding to 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 status” command.
