Printer ID - ``$1D $49`` |rel| |phx|
-------------------------------------

    Short description

    :Format: 
             ``Hex      $1D $49 n``

             ``ASCII    GS  I   n``

             ``Decimal  29  73  n``
    :Notes:
        - This command responds when the data buffer is processed. Therefore, a time delay between when the command is received and when the printer responds can occur. This time delay depends on the data buffer status and printer status.

        - Refer to this table for valid values of ``n``:

        - Phoenix only supports the ``n=3`` parameter.

.. _1d72:

Transmit Status - ``$1D $72`` |rel|
---------------------------------------------

    Transmits the paper sensor status based on the value of ``n``. 

    :Format: 
             ``Hex      $1D $72 n``

             ``ASCII    GS  r   n``

    :Notes:
        - This is **not** a real time status command. 
        - Commands will be processed in order of reception, therefore a time delay may be present between receiving the command transmitting the Paper Sensor Status.
