In a printing method and systems, segments of a first print job are distributed to respective downstream processors and are processed to provide printable frames, which are stored in respective print queues. Each print queue supplies a respective one or more printheads. The printable frames are sequentially printed on a continuously transported receiver. A maximum printing duration of each of the print queues is computed periodically during the printing. The transport speed is regulated to trend the maximum printing durations toward a predetermined baseline. The sending of a second print job to the downstream processors is delayed, while processing of the first print job is completed. The delaying is counter to the regulating and reduces the print queues of the first print job non-uniformly relative to the baseline.
