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 it receives from the computer as hexadecimal values.

You can print a hex dump using either single sheets or continuous paper. See Chapter 3 for instructions on loading continuous paper, or Chapter 4 for instructions on loading single sheets.

Note:

Use paper that is at least 210 mm (8.3 inches) wide, such as A4 or letter size paper.

To print a hex dump, follow the steps below.

1. Make sure paper is loaded and the printer is turned off.

Caution:

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

2.To enter hex dump mode, hold down both the LF/FF and Load/Eject buttons while you press the Operate button to turn on the printer.
