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