Print job management information, including management actions performed by a press operator, is collected from a print job manager. An evaluator evaluates the collected print job management information using an evaluation algorithm to generate a predicted press-operator job release sequence of one or more of the print jobs. The evaluation algorithm may be adapted to predict print job release behavior of the press operator. A print job is selected in accordance with the predicted press-operator job release sequence. Print job preprocessing of the selected print job is initiated in the printing system, prior to actual release of the print job by the press operator. Actual print-job release information may be compared with a predicted job release sequence to revise the evaluation algorithm.
