Hexadecimal Dumping Mode - Epson C31CE94061N Technical Reference Manual

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.
 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.

numbers and ASCII characters.
