3. Open a software program and send a print job to the printer.
Your printer prints all the codes it receives in hexadecimal
format.
By comparing the characters printed in the right column with
the printout of the hexadecimal codes, you can check the
codes being received by the printer. If characters are printable,
they appear in the right column as ASCII characters.
Nonprintable codes, such as control codes, are represented by
dots.
4. To exit the hex dump mode, press the Pause button and eject
the printed page(s), and turn off the printer.
