Optimizer for dual modules that process dependent channel print streams

Two or more dependent print streams destined for individual print stream processing modules are optimized by processing the data for the print streams prior to printing. The process of optimizing includes receiving an input representing a plurality of documents to be printed and determining an attribute of each document of the plurality of documents represented by the input. The attribute relates to processing of the respective document through the document processing system. Optimization involves balancing an operation time of the first print stream processing module with an operation time of the second print stream processing module, by assigning the plurality of documents to the one or more print streams such that each document having a page count higher than one is processed in part by the second print stream processing module concurrently with a number of available single page documents and the first page of each document having a page count higher than one being processed by the first print stream processing module, the number of available single page documents being approximately equal to the sum total of the documents assigned to the second print stream.
