    Is it possible to make a program which can write to that parallel port
    buffer/register which stores the input data to the parallel port (from
    the printer). In effect, I am trying to manipulate the data registers
    of the parallel port.
     That is, without an external device sending input data to the port,
    is it possible to fill the buffer with data so as to make the
    operating system into believing that an external device is connected.

    Also please specify when this can be done,that is:-
    1) can I manipulate the data the BIOS reads/stores
    2) can I manipulate the data the O.S reads on booting.
    3) can this be done once the O.S. is loaded and running.

    Thanks
