Parallel Interface
There are two parallel interface cards available. One is a 25-pin, D-shell connector. The pin-out is such that the
printer interfaces to a standard IBM PC parallel printer interface with a one-to-one cable. The second interface card
provides the same interface with a standard, 36-pin Centronics type connector. Both cards provide a dual cash
drawer interface. The tables below lists interface signals and pin definitions for both types of parallel interfaces.
