The invention relates to a printer for printing a substrate (12), comprising a print unit and a supply unit for holding a substrate and delivering said substrate for transport to the print unit, wherein the supply unit is provided with a member for receiving a core (11) on which the substrate is wound, such that after reception by the member said core is functionally connected to a motor (200) for rotatably driving the core, and a downstream transport nip (31) for engaging and transporting an unwound part of the substrate which nip for the driving thereof is functionally connected to the said motor, wherein the transmission from the motor to the core and the nip respectively is such that on transport of the substrate to the print unit only the nip is actively driven by the motor and on the return of the substrate for winding thereof on the core both the core and the nip are actively driven by the motor, the core winding up as many metres of substrate per second as the nip returns.
