Hexadecimal dump
This procedure prints in hexadecimal format all codes (character codes and
control codes) that are sent to the printer by the computer. The printer does not
execute any control codes (such as 0A - linefeed), it just prints them out. The
hexadecimal dump is useful when you are writing programs for printer control.
❏ Turn off the printer.
❏ Make sure that paper is loaded in the printer.
❏ While holding down the control panel’s LINE FEED button, turn the
printer back on to enter the Hex Dump Mode.
❏ To exit the Hex Dump Mode, turn the printer off.
