Printing a Hex Dump
If you are an experienced user or a programmer, you can print a
hexadecimal dump to isolate communication problems between
the printer and your software program. In hex dump mode, the
printer prints all data received from the computer as hexadecimal
values.
You can print a hex dump using either single sheets or continuous
paper. See Chapter 2 for instructions on loading continuous
paper, or Chapter 3 for instructions on loading single sheets.
Note:
Use continuous paper that is at least 241 mm (9.5 inches) wide or A4 or
letter size single-sheet paper.
To print a hex dump, follow the steps below.
1. Make sure paper is loaded and the printer is turned off.

Caution:
Whenever you turn off the printer, wait at least five seconds
before turning it back on; otherwise you may damage the
printer.
