<p>A resource oriented host computer-printer system is disclosed in which t he host computer and printer share information and data processing duties. A system and method for analyzing the execution times for draw primitives allows the host computer to determine whether the printer will be able to render draw primitives in real - time. The inventive system sends a series of test instructions to the printer at the time the printers is installed on the host computer. A timer is used to time a predetermined peri od of time during which the draw primitives are sent to the printer for execution. Based on th e number of draw primitives executed and the type of draw primitives executed, the system constructs a printer model. A log file is used to store the acquired cost metric data. In one embodiment of the invention, a clumping procedure is used to classify cost metric data. A seri es of cost tables stores the classified cost metric data. A map table provides a map to the co st table to speed up the process of cost metric data retrieval. At run time, a resource assembler calculates the cost of executing each draw primitive within a band to determine if the printer can render the draw primitive in real-time. If the band is too complex for the printer to render in real-time, the host computer will render the band and transmit the bit-map of that band to the printer. If too many bands on one page are complex, the host computer may render the entire page and transmit the bit-map for all bands on the page.</p> |
