Table 2. IEEE 1284 Connector Pinouts.

When connecting a 1284-A host to a 1284-B peripheral the “Peripheral Logic High” signal is not used. Similarly, when

a 1284-A host is connected to a 1284-C peripheral the “Peripheral Logic High” and “Host Logic High” are not used.

These two signals are optionally used to detect a “Power Off” or “Cable Disconnect” state for host and peripheral

respectively.
