Before the advent of printers with USB connections, the dominant standard was IEEE 1284, aka the "parallel printer interface".

This parallel printer cable provides the most common printer connection with a DB25 male connector on one end, to connect to the computer's parallel port, and a Centronics CN36 male connector on the other end, to connect to the printer's parallel port.

The 25 conductors in this cable provide individual signal connections and shared return grounds for the remaining 8 conductors. The connector heads are molded onto the cable and the DB25 end has thumbscrews for securing the connector to the computer, while the CN36 end has metal clip receptacles for securing it to the printer.
