Hexadecimal dumping mode
In hexadecimal dumping mode, data from the host computer is printed in hexadecimal numbers and charac-
ters. By comparing the print outs and the program, you can check whether or not data is being sent to the
printer correctly.
Make sure no errors have occurred and that the printer is not off-line.
Pairing is possible for one minute after printing the status sheet.

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.
