Abstract
A host computer and printer and method of operation in which the data file describing a document is examined by a resource assembler which determines which resources are required from the host computer to print the document. The resource assembler translates the document into a set of render primitives for each band or page of the document and creates a dependency list interrelating the required resources with each band or page. The resource assembler places the required resources and set of primitives into a host resource store and communicates the dependencies to other portions of the system. A resource loader uses the list to determine the most efficient manner for loading and releasing resources from a printer resource store. A resource scheduler controls the actual timing of resource and primitives transfer and determines when all required resources for a band or page are present within the printer resource store. The resource scheduler generates an execute signal which causes a resource executor to convert the primitives to a bit-map data file. The resource assembler may convert the primitives to a bit-map data file if the resource executor cannot convert the primitives in re…
