Abstract: A system and a method for encrypting print job data. Encryption takes place in the data-communication region within a print job system which lies between a source for print job data, and the ultimate recipient thereof. Preferably, encryption takes place in a location of data de-spooling, such as in the vicinity of a print processor, a spooler, a print assist, or a port manager.

Abstract: A system and method are provided for adaptively allocating random access memory (RAM) in an multifunctional peripheral (MFP) device with a plurality of components. The method comprises: supplying an interface; and, in response to interface prompts, selecting the allocation of RAM for MFP features or components. Typically, the MFP device includes fax, scanner, printer, and copier components, and the method further comprises selecting the allocation of RAM for MFP components selected from the group including fax, scanner, printer, or copier. The method further comprises: selecting the allocation of RAM for MFP features selected from the group including post script (PS) documents, printer control language (PCL) documents, tagged image file format (TIFF) documents, or portable document format (PDF) documents.
