ENERGY SAVER NETWORK PRINTING SYSTEM (Cont'd)

An energy saving protocol for a local area network comprising a plurality of personal computer work stations connected to a plurality of printers through a network server is disclosed, wherein customer designated job priority can be exploited to significantly reduce energy consumption. As shown in the accompanying figure, the presently disclosed network printing system comprises a plurality of printers interconnected through a communication link such as a server which interconnects the printers to a plurality of personal computer-type work stations. In a typical working environment, individual work stations are present at various locations within the network, from which inputs for print jobs are entered into the network. Likewise, a plurality of printers are typically present at various locations within the network from which print jobs from various work stations can be received. The work stations can be in the form of a personal computer system, a visual display terminal with minimal input output capabilities and no processing capabilities, or one of various input/output devices.

An energy saving system is proposed, wherein each print job may be assigned a selective job priority by the operator at the PC work station such that print jobs can be batched in accordance with an assigned job priority. Information relating to each print job...
