1. A printing press comprising a non-impact printing device (13), the printing press further comprising a plurality of processing stations for processing sheets (77); the plurality of processing stations arranged along a transport direction (T) of the sheets (77); a first processing station of the plurality of processing stations comprising the non-impact printing device (13); the first processing station or a second processing station of the plurality of processing stations comprising a first transport device that transports the sheets (77) along a first linear transport section, the first transport device comprising at least one first conveyor belt (16) that continuously revolves and that is diverted at a rotating diverting roller (76); the first transport device being configured to transport adjacent individual sheets (77) that directly follow one another in a sequence lying flat on the at least one first conveyor belt (16); a second transport device transporting the sheets (77) lying flat along a second linear transport section, on at least one second conveyor belt (18) that continuously revolves and that is arranged downstream in the transport direction (T) from the first or second processing station comprising the first transport device; a discontinuity point (78) in mechanical support of the sheets (77) to be transferred being formed at a location at which the sheets (77) to be transported are transferred from the at least one first conveyor belt (16) of the first transport device to the relevant at least one second conveyor belt (18) of the second transport device following in the transport direction (T) of the sheets (77), in a conveying plane (E19) of the sheets (77) to be transported; the diverting roller (76) diverting the at least one first conveyor belt (16) of the first transport device being arranged at the discontinuity point (78) in the mechanical support of the sheets (77) to be transferred; a guide device (42), which extends transversely to the transport direction (T) of the sheets (77) and comprises a tapered profile element (79), being arranged at the discontinuity point (78); the guide device (42) being arranged at the discontinuity point (78) between the at least one first conveyor belt (16) and the at least one second conveyor belt (18) arranged consecutively in the transport direction (T) of the sheets (77); a tip of the profile element (79) being oriented toward the at least one first conveyor belt (16) of the first transport device counter to the transport direction (T) of the sheets (77); the tip of the profile element (79) being spaced apart from the at least one first conveyor belt (16) by a gap between the tip and the at least one first conveyor belt (16); the gap between the tip of the profile element (79) and the at least one first conveyor belt (16) having a width in a range between 1 mm and 5 mm; a control unit (71) and at least one lifting nozzle (43) being provided; and a third processing station of the plurality of processing stations, that is arranged directly downstream from the first or second processing station, being configured as a suction belt feed table (19), characterized in that the at least one lifting nozzle (43) is arranged in the profile element (79) of the guide device (42), the at least one lifting nozzle (43) being configured to open in a direction of the tip of the profile element (79), the suction belt feed table (19) comprising a catching device (58) having a catching position, which is assumed as a result of an actuation, for adjacent individual sheets (77) that follow one another, and the catching device (58), in the catching position, catching the sheets (77) on the suction belt feed table (19) that are fed from the first transport device (18), which is arranged upstream from the suction belt feed table (19), to the suction belt feed table (19) before being transferred to a transport device arranged downstream from the suction belt feed table (19), and stacked.
