ABSTRACT:
An image buffer for use with laser imagers is configured to receive image signals from a raster image processor (RIP). The image buffer comprises a two by two data switch and two memories for storing image data signals as generated by the RIP. The stored image data signals are presented to the laser imager in accordance with command signals provided by an image buffer controller. The image buffer controller utilizes a video interface that includes a SCSI controller and line buffer to reformat the stored image data signals before presentation to the laser imager, thereby allowing for independent operation of the RIP and laser imager.
