These commands remove any data in the printer's buffer and return the printer to the current
menu settings. They will override any features set on the printer's front panel or through
previous commands. Also known as the initialize printer or reset commands.
Note: In order for this command to be effective, the Reset Inhibit item in the printer Menu
must be set to NO (the factory default). If the setting has been changed to YES, this
command will be ignored.
