A door pressing system for pressing interior passage doors, exterior entry doors, bi-fold doors, and/or closet doors features a multi-door pressing station including first and second presses, a loading device, and a discharging device. The pressing station is configured to alternatively move the first and second presses into operative alignment with the loading and discharging devices. The press in operative alignment delivers a pressed assembled door to the discharging device and receives an assembled door layup to be pressed from the loading device. The other press that is out of operatively alignment presses an assembled door received therein. Additional methods and systems are also provided.
