Abstract

In a method or controller to execute a proof job of a copy print job, the proof job including a printing of a proof sheet, at a first point in time first raster data for the print sheet of the copy print job is provided. After expiration of a first provisioning time period at least one first job is inserted for printing a plurality of copies of the print sheet into a print buffer. A second point in time is determined at which the print buffer includes a first number of copies of the print sheet that are to be printed, the first number being such that a time period for printing of the first number of copies is greater than or equal to a second provisioning time period for providing of second raster data for the proof sheet of the proof job. After expiration of the second provisioning time period a second job is inserted to print the proof sheet into the print buffer so that copies of the print sheet and the proof sheet are printed according to an order of the first and the second jobs in the print buffer.
