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 the printer is receiving. 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 turn off hex dump mode, press the Pause button, and then turn off the printer.
cCaution:
Do not turn off the printer while it is printing the hex dump. Always press the Pause button to stop printing and then turn off the printer.
