Abstract: A user interface for a document processing system includes a scheduler adapted to calculate and display an expected processing time for a job to be processed. The scheduler has an input device permitting a user to input a calibration command causing the scheduler to apply a user-specific calibration function to the calculated expected processing time.

Abstract: A print system includes a print engine for printing on sheets of receiving material. A user interface unit includes a display. A plurality of holders each hold one type of receiving material and deliver the material to the print engine. A receiver receives jobs, a job being an order for printing information on sheets of receiving material of a type as specified in the order. A control system plans jobs, wherein the jobs are placed in a print queue in a sequence of finishing, the control system also being provided with a device configured to establish the types of receiving material required for printing the respective jobs in the print queue. The control system is adapted to establish, for a type of receiving material, a shortage quantity, if any, of that receiving material, for completely printing the jobs, and to indicate the shortage quantity on the display of the user interface.
