Abstract
A printing system for printing several types of data on the same page, regardless of any differences in spot density between data types. This circuit provides a separate channel for each data type and processes each data type according to its own instructions and parameters (halftones, compressed images, font generation, etc) and according to its own spot density, without there being a necessity for there to be any synchronous relationship between x and y spot densities of the plurality of data types. Each channel has a boundary checker to determine whether the data is within the image boundary by comparing the x/y coordinates of the scanning beam to the input boundary data, and a data converter to convert the data according to its own instructions. Finally, the output of the channels is combined to form the data stream that is sent to the printer.
