Status Messages of the Printer through the

interfaces:

Besides the optical status messages displayed by the

three LEDs on the control panel of the printer, messages

are also transmitted through the BT interface. Most of the

time, they are sent as single ASCII characters that can be

analyzed by the host.

The following table shows all status messages.
