Hexadecimal Dumping Mode

In hexadecimal dumping mode, data from the host device 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.
Follow the steps below.
1
Open the roll paper cover.
2
While pressing the Feed button, turn on the printer. (Hold down the Feed button
until the Error LED turns on.)
3
Close the roll paper cover.
From this point, all data received by the printer is printed in the corresponding hexadecimal num-
bers and ASCII characters.
Example of printing in hexadecimal dumping mode:

 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 status" command.
