摘要： A resource oriented host computer-printer system is disclosed 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.
摘要翻译： 公开了一种面向资源的主机 - 打印机系统，其中主计算机和打印机共享信息和数据处理任务。 用于分析绘图图元的执行时间的系统和方法允许主机计算机确定打印机是否能够实时绘制绘制图元。 如果打印机无法实时绘制绘图图元，则主机可能会发送要由打印机预渲染的绘图图元。 渲染在不到三十秒内完成。 主机可以确定绘图原语的执行时间，并相应地动态地更改超时时间。 如果打印机超过确定的执行时间，主机会生成超时错误消息。 由于超时时间与打印机所需的实际处理时间有关，主计算机不会生成虚假超时错误消息。 如果打印机耦合到网络，则由于主机可能不与打印机连续通信，所以超时时间可被设置为最大三十秒。 主计算机仍然不会产生虚假超时错误，因为最大超时时间仍然与打印机所需的实际处理时间有关。 本发明的系统和方法适用于使用超时时间的任何外围设备。
