摘要： A printer driver uses filters that are operating system-independent and printer-independent. Print requests and corresponding print data are received by the printer driver and converted into an internal representation that is both operating system-independent and printer-independent. The data to be printed is then passed through a print pipeline where one or more of a plurality of print filters are applied to the data. As a final stage in the print pipeline, the data is converted to a printer-dependent representation. In one embodiment, one or more of the plurality of filters used in the print pipeline are stored in a dynamic link library (DLL).

摘要： A system for processing a print job stores the print job on a first device. A pointer is provided to a printing device, which notifies the printing device that the print job is waiting to be processed. The pointer also identifies the name and location of the print job stored on the first device. When the printing device is ready to process the print job, the printing device retrieves the print job from the first device using the pointer. Additionally, the printing device may retrieve a particular font prior to processing the print job.

摘要： Memory fragmentation in a page printer is avoided by assessing the current extent of memory fragmentation and memory utilization before allocating memory for describing a portion of a next page to be printed. In one embodiment, the assessment includes a weighted average of a normalized standard deviation of current free memory block sizes (indicating fragmentation) and the current percent utilization of memory. A page printer in one embodiment has insufficient memory for bit for bit images of entire pages to be printed. However, a high page printing rate is nonetheless maintained by avoiding interruptions in interface communications and data processing that result when there is insufficient memory to support an allocation request for a contiguous block size. Memory allocation for a new page to be printed is deferred until an assessment of memory fragmentation and utilization is favorably compared to a limit. Processing of a new page with consequential increased fragmentation and increased utilization is, therefore, begun at a time when a memory-out condition and subsequent delays are less likely to arise.
摘要翻译： 通过在分配用于描述要打印的下一页的一部分的内存之前评估当前的内存碎片和内存利用程度来避免页面打印机中的内存碎片。 在一个实施例中，评估包括当前空闲存储器块大小（指示分段）的标准化标准偏差和存储器的当前百分比利用率的加权平均值。 一个实施例中的页面打印机对于要打印的整个页面的位图像的位不足， 然而，尽管如此，通过避免在没有足够的内存支持对连续块大小的分配请求的情况下导致的接口通信和数据处理中断的情况下，保持高页面打印率。 要打印的新页面的内存分配将推迟到内存碎片和利用率的评估与限制相比有利。 因此，新的页面的处理因此增加了碎片和增加的利用率，因此在缺少出现条件和随后的延迟不太可能出现的时候开始。

摘要： A method for configuring data communication paths between a central controller and a plurality of devices is provided. The method ensures a first appliance is active. For each of the devices, a first communication capability is determined between the first appliance and the device. Signals indicative of the first communication capabilities are transmitted to the central controller. Respective communication paths are mapped between the central controller and the devices via the first appliance as a function of the first communication capabilities. The method ensures an automatic appliance failover is obtained.

摘要： A print job requiring unavailable resources is held until the deficiency is remedied. The resource requirements of the print job are evaluated. The resource requirements are compared to known available resources. Either standard resources are assumed or available resources for the printer are discovered. Responsive to a resource deficiency exposed by the comparison, the print job is communicated to a printer with a command to hold the print job. Also responsive to the resource deficiency exposed by the comparison, instructions for remedying the resource deficiency are created and the instructions are provided to a remedy provider. The instructions are provided to the remedy provider either by printing the instructions or by displaying the instructions on the printer. The remedy provider remedies the resource deficiency and the printer processes the print job. Alternatively, the resource deficiency is communicated to the printer, the resource deficiency is monitored for a remedy, and responsive to the remedy of the resource deficiency, the print job is processed.
