Patent number: 12151492Abstract: A printer for outputting a printed product includes: a print head for printing on a print medium moving in a longitudinal direction, the print medium including a plurality of separate or separable labels detachably arranged on a carrier along the longitudinal direction; and a material interface for outputting the print medium printed by the printer as a printed product, the material interface including a dispensing edge and a support, which deflect the carrier over the dispensing edge and the support downstream of the print head in the longitudinal direction. The dispensing edge is arranged relative to the support in a first position to induce a detaching deflection of the carrier for detaching the respective label. The dispensing edge and the support are arranged in a second position relative to each other to induce an entraining deflection for entraining the respective label on the carrier.Type: GrantFiled: October 6, 2020Date of Patent: November 26, 2024Assignee: PHOENIX CONTACT GMBH & CO. KGInventors: Kilian Klages, Alexander Hofmann, Michael Peter, Albrecht Schierholz
