Notes:
Changes in DIP switch settings (excluding switches 2-7 and 2-8) are recognized
only when the printer power is turned on or when the printer is reset by using
the interface. If the DIP switch setting is changed after the printer power is
turned on, the change does not take effect until the printer is turned on again
or is reset.
If DIP switch 2-7 or 2-8 is turned on while the printer is turned on, the
printer may be reset, depending on the signal state. DIP switches should not be
changed while the printer power is on.
