Hexadecimal Dumping Mode - Epson TM-T20II-i Technical Reference Manual

Hexadecimal Dumping Mode

In the hexadecimal dumping mode, the printer prints the data transmitted from a host computer in
hexadecimal numbers and their corresponding characters.
Follow the steps below to run this mode.
 If there is no character corresponding to print data, "." is printed.
 If print data is less than one line, press the Feed button to print the line.
 Applications that confirm printer status may not work correctly during the hexadecimal dump-
ing mode. The printer returns only the status for "Transmit real-time status."
Follow the steps below.

After this, all the data received by the printer is printed in hexadecimal numbers and their cor-
responding ASCII characters.
