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.
Note:
Use continuous paper that is at least 241 mm (9.5 inches) wide or A4 or
letter size single-sheet paper.
