    摘要: Use of a single pass print data stream conversion process when sufficient memory is available to store all the page data to be printed and reversion to a double pass conversion when insufficient memory is available. Scanning of the input data stream, storing the page data, and downloading the resource data to the printer continues so long as sufficient memory to store the page data is available. If the available memory is filled before the entire page is scanned, the stored page data is discarded. The scanning continues to download the resource data but the page data is no longer stored. When the page has been completely scanned, the scanning is restarted at the beginning of the page, downloading the page data to the printer and discarding the resource data during the second scan.

    摘要翻译: 当有足够的内存可用于存储要打印的所有页面数据并返回到双通道转换时,使用单次打印数据流转换过程,当内存不足时。 只要足够的存储器来存储页面数据就可以扫描输入数据流,存储页面数据和将资源数据下载到打印机。 如果在扫描整个页面之前填写了可用的内存,则丢弃所存储的页面数据。 扫描继续下载资源数据,但不再存储页数据。 当页面被完全扫描时,扫描将在页面开始重新启动,将页面数据下载到打印机,并在第二次扫描期间丢弃资源数据。
