The invention relates to stacking logistics for a printing machine to print the front side of sheet and the reverse side of a sheet. The aim of the invention is to create stacking logistics for a printing machine whereby the front side of a sheet is printed first, followed by the reverse side of a sheet. According to the invention, this is achieved by putting the stacks on conveyor trolleys assigned to a common stacking plane and placing a cantilever arm with a vertical drive mechanism in the side areas of the feeder stack and the exit stack on both sides, symmetrical to the machine's longitudinal axis and locating it below the respective assigned conveyor trolley.
