Pre-processing unit for documents to be printed, system including such a pre-processing unit, and method for pre-processing documents

摘要

A document pre-processing unit for pre-processing documents to be printed. The unit has a processor input for receiving document data at least representing content. A computing unit is connected to the processor input, for computing a number of sheets a physical document would include if printed in accordance with the document data. In a memory threshold information can be stored. A comparing unit is connected to the computing unit and the memory, for outputting a modify signal if the computed number exceeds a threshold determined from the threshold information. A data modify unit is connected to the comparing unit, for reducing the computed number of sheets below the threshold by modifying the document content and/or the lay-out of the document in response to the modify signal. A processor output is connected to the data modifying unit for outputting the modified document data.
