Before the advent of printers with USB connections, the dominant standard was IEEE 1284, aka the "parallel printer interface". If you have a computer and printer with this interface, you can depend on Monoprice to stock the cables you will need to connect them! This parallel printer cable features a DB25 male connector on each end. Each pin provides a straight through connection to the same pin number on the other end. The connector heads are molded onto the cable and each end has thumbscrews for securing the connectors to the DB25 ports.
