parallel port wiring confusion

    Most of the pinouts for various cables I've come accross do not denote
    wether the connections are for the parallel port or the parallel port cable
    connector.
    Is the numbering scheme on a female connector different than a male
    connector?
    If someone could explain how parallel wiring works that would be great.

    Thanks

  3. The pin numbers on the male and female DB-25 connectors are the same -
    when mated, male pin 1 connects to female socket 1 (and the same
    applies to any other connector family I've used).

    On some _cables_, pin x on one end is not connected to pin x at the
    other - in a "Null Modem" serial cable, pin 2 at one end is connected
    to pin 3 at the other, and verse visa (and several other connections
    are swapped).

    If you have a cable with different types of connectors at each end
    (like an old PC printer cable, with a DB25 at one end, and a 36way
    Centronics at the other), it is fairly unlikely that connections will
    be pin-to-pin.
