System and method for dynamic printer timeout
First Claim
1. A computer-printer system including a printer and a host computer for controlling and printing a document on the printer, the host computer having a resource storage area for storing resources, a plurality of resources stored in the resource storage area, and a data file for the document containing data describing a plurality of objects to be printed, the printer containing a print engine, the system comprising:
- a host resource store within the host computer storing a selected set of resources comprising a plurality of the resources required to print the document;
a resource assembler within the host computer examining the data file and selecting at least some of the resources from the resource storage area to form a subset of selected resources required for printing the document, loading said subset of selected resources in said host resource store, translating the data file into a set of primitives corresponding to the plurality of objects within a particular portion of the document, calculating a rendering cost for rendering said set of primitives into a bit-map data file within the printer, and setting a timeout period at least as great as said rendering cost;
a printer resource store within the printer receiving said subset of selected resources and said set of primitives from the host computer and storing said subset of selected resources and said set of primitives;
a resource scheduler within the printer controlling transfer of said subset of selected resources and said set of primitives to said printer resource store, said resource scheduler maintaining communication with the host computer during the transfer of said subset of selected resources and said set of primitives; and
a resource executor within the printer creating said bit-map data file corresponding to said subset of selected resources and said set of primitives and transferring said bit-map data file to the print engine for printing, whereby said timeout period corresponds to the actual rendering time.

Abstract
A resource oriented host computer-printer system in which the 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. If the printer cannot render the draw primitives in real-time, the host computer may send the draw primitives to be pre-rendered by the printer. The rendering is accomplished in less than thirty seconds. The host computer can determine the execution times for the draw primitives and dynamically alter the timeout period accordingly. If the printer exceeds the determined execution time, the host computer generate a timeout error message. No false timeout error messages are generated by the host computer because the timeout period is related to the actual processing time required by the printer. If the printer is coupled to a network, the timeout period may be set to the maximum thirty second period because the host computer may not have continuous communication with the printer. The host computer will still not generate false timeout errors because the maximum timeout period is still related to the actual processing time required by the printer. The inventive system and method are applicable to any peripheral in which a timeout period is used.
