Parallel I/O Port Connector (J7)
The interface for the parallel port is a standard IEEE P1284-C, 36-pin
connector, J7. The functionality of each signal depends on the mode of
operation of this bidirectional Parallel Peripheral Interface. Refer to the
IEEE P1284 D2.00 Standard for a complete description of each signal
function. The connector shield is tied to chassis ground.
