摘要： In a dual engine printing system producing a multipage print job from first and second serially connected printing engines at a common output from the second engine, where the second printing engine has a duplex return path bypassing its printing path and extending substantially therethrough, a high productivity simplex job printing mode is provided in which alternate pages are substantially simultaneously printed in both the first and second printing engines, but the alternate pages printed in the first printing engine are fed to the second printing engine duplex return path to bypass the printing path of the second printing engine and then are automatically interleaved in the common output with the alternate pages printed in the second printing engine. The duplex return path is preferably a bidirectional loop extending above the printing path and driven in a reverse sheet feeding direction for this simplex printing. In an alternate duplex job tandem printing mode, sheets printed on one side in the first printing engine are inverted and fed directly to the printing path of the second printing engine for printing their opposite sides and outputted directly to the common output. Both printing engines may be substantially identical and capable of independent duplex printing with the duplex return path driven in the forward sheet feeding direction.

摘要： A method and system is provided for partial job interrupt of an on-going first print job to cause a contemporaneous parallel printing of a second print job. A plurality of marking engines associated with the storage device for receiving and storing a plurality of print jobs in queue, executes a first print job and outputs the sheets to an assigned first sheet output. A user determines that a second print job sent to the system and stored in the queue behind the first print job will be undesirably delayed and so interrupts the first print job by limiting the executing of the first print job to less than all of the plurality of print engines within the printing system. An output of the first print job is maintained at the first job sheet output. The second print job can then be contemporaneously executed with the execution of the first print job with available print engines interrupted from the first print job. Second print job sheets are outputted contemporaneously at a second sheet output with the output of the first print sheet jobs. The partial job interrupt is effected at the printing system upon detection by user of a delay in the printing of the second print job. The limiting of the executing of the first print job could also be effected by contemporaneously applying images of the first print job and the second print job to the photoreceptor of a one of the marking engines.
摘要翻译：提供了一种用于正在进行的第一打印作业的部分作业中断的方法和系统，以使得第二打印作业的同时并行打印。与存储装置相关联的用于接收和存储队列中的多个打印作业的多个标记引擎执行第一打印作业并将纸张输出到分配的第一纸张输出。用户确定发送到系统并存储在第一打印作业后面的队列中的第二打印作业将被不期望地延迟，并且因此通过将第一打印作业的执行限制为小于所有多个在打印系统中打印引擎。第一打印作业的输出保持在第一作业表输出。然后可以与第一打印作业的执行同时执行第二打印作业，其中可用的打印引擎从第一打印作业中断。第二打印作业表与第一打印纸作业的输出在第二纸张输出同时输出。当打印系统在第二打印作业的打印延迟时被用户检测到，部分作业中断被实现。第一打印作业的执行的限制也可以通过同时将第一打印作业和第二打印作业的图像同时应用到一个标记引擎的感光体来实现。
