This reports the current asserted state of an input signal identified by paraInSigName: none(1), on(2), or off(3). An admin monitors this to detect real-time hardware conditions on the printer connection, such as whether the paper-out or fault signal is currently asserted, without needing to physically inspect the device. For example, a paraInSigState of on(2) on the row where paraInSigName is fault(5) would alert an admin to a hardware fault condition on that printer port.
