Abstract: A printing machine, which is configured as a printing tower having a plurality of printing units, is usable for double-sided, multicolor printing. A device that is usable for controlling the temperature of the components of one or more of the printing couples is provided. Each printing unit includes a plurality of printing towers that are disposed vertically one over the other. Each of these printing devices has at least one component that is to be temperature controlled and which has a thermal interaction with a fluid of a secondary circuit by way of an inlet. The secondary circuit can have fluid of a primary circuit entered by a feeding station for controlling the temperature. Components that are to be temperature controlled, and that are part of at least two different printing devices, have thermal interactions with two secondary circuits that are different from each other.
