SCSI-I on a centronix connector is 50 pins with 25 grounds. Apple hijacked
a DB-25-S to do their SCSI-I where the grounds were all tied to one pin.

SCSI-II uses a high density 50 pin connector. Differential SCSI uses the 68
pin connectors.

Note that these are all external connections. Internal connections
typically use 50 or 68 pin 0.1" headers and connectors.

Parallel printer connections use a centronix connector with 36 pins.

The print pack does not use RS-232 or SCSI, nor USB or even I2C.
