    Are you sure there aren't two serial ports for this BT connection, one to
    receive (read)- also called 'outgoing', and another to send (write) - also
    called 'incomming'?

    In this case, you'd need two separate instances of the serial port object,
    one to send and the other to receive.

    Note, I haven't used your printer, so I'm speculating (often BT devices
    assign a single SPP port), and if this isn't the case, I don't have another

    normally you can send and receive over the same Bluetooth SPP
    connection. This distinction sending or receiving SPP port (dev A/dev B)
    is only relevant for the initiation of the communication. Later it's
    unrelevant. I assume the communication is started by the CE device and
    not the printer.
