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 Labels for instructions on loading continuous paper, or Loading Single Sheets in the Top Paper Slot 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.
Follow these steps to print a hex dump:
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.
To enter hex dump mode, hold down both the LF/FF and Load/Eject buttons while you turn on the printer.
Open a software program and send a print job to the printer. Your printer prints all the codes it receives in hexadecimal format.
If characters are printable, they appear in the right column as ASCII characters. Nonprintable codes, such as control codes, are represented by dots. By comparing the characters printed in the right column with the printout of the hexadecimal codes, you can check the codes the printer is receiving.
To exit hex dump mode, press the Pause button to stop printing and the Load/Eject button to eject the printed page(s). Then turn off the printer.
