Abstract
An interface provides rasterized data to an imaging device such as a color copier or laser printer. Rasterized image data received from a raster image processor is compressed and stored in an output queue until the imaging device is ready to receive an image represented by the data. A data output path between the output queue and imaging device communicates the rasterized image data to the imaging device. The compressed rasterized image data is decompressed within the data output path as the data is being communicated to the imaging device. Throughput of the imaging device is maximized by actuating the device to operate in a multiple copy mode while rasterized image data for different image pages is successively communicated to the imaging device. An abort command prevents the imaging device from processing extraneous substrates when running in a multiple copy mode. Image processing is provided to selectively dilate objects contained in images represented by the rasterized image data, thereby compensating for potential multi-pass misregistration errors in the imaging device.
