FIBRE CHANNEL DATA TRANSFER WITH FEEDBACK CONTROL WITHIN A PHOTOGRAPHIC PROCESS PRINTER SYSTEM

摘要

In a photographic process printer system that receives printable pixel data into a print engine component from a computer component (100) over a high-speed fibre channel (120) communication pathway. Feedback control messages from the print engine component are sent over a low-speed serial channel (122) communication pathway to the computer component (100) to control the transmission of printable pixel data. The computer component (100) continues to transmit packets of printable pixel data over the high-speed fibre channel (120) communication pathway as long as the feedback control messages indicate that the print engine component is ready to receive more packets of printable pixel data.
