In a printing system or method a first printing apparatus and a second printing apparatus are respectively selectively operable in simplex mode and duplex mode. Each of the printing apparatuses in simplex mode process print jobs independently of the respective other printing apparatus, and in duplex mode processing print jobs jointly by both of the printing apparatuses. The printing apparatuses are connected with one another for control at least in duplex mode. An activation operating unit is provided via which at least one of the two printing apparatuses is selectively activated for the simplex mode or both of the printing apparatuses are selectively activated for the duplex mode.
