Abstract: Examples include a printing machine configured as a non-impact printing machine and that includes at least one print head and a roll unwinding device. A transport path is provided for transport of a printing substrate that is assigned to the printing machine. At least one charging electrode is configured as a DC voltage electrode. An area of the transport path provided for the transport of the printing substrate and that is closest to the at least one charging electrode is arranged upstream from a printing nip defined by the print head. The central cylinder is grounded and the print head is grounded. A smallest distance between at least one ejection opening of the print head and the at least one charging electrode is at least 20 mm.
