US Patent 7847967 Adaptive de-spooling system for partial brute force collation

A system for partial brute force collation of a print job includes a printing device having ROPM capability and memory. The printing device receives at least a portion of the document from a source device. The memory stores at least a portion of the document. The printing device has a memory printing mode and a brute force collation mode. In the memory printing mode the portion of the document stored in memory is printed. In the brute force collation mode any portion of the document not stored in memory is printed. The system can also alternate between the memory printing mode and the brute force collation mode for each of the N copies of the electronic document of the print job such that the resulting printed output is collated.
