Parallel Port

Most ThinkPads have a Female DB-25 Parallel Port, for ThinkPads produced from 1995 on they are IEEE1284 compliant.

The latest ThinkPads no longer have a physical parallel port, but still have the logic integrated, all that is required is to attach the ThinkPad to a supported Dock or Port Replicator with a parallel port.
