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.
 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.
