    • A page printer includes a variable frequency clock for producing at least two clock frequencies, one higher than the other. The page printer includes a first memory for storing a page processing procedure and a second memory for storing data comprising full page strips. A processor operates at the first clock frequency in conjunction with the page processing procedure and derives a rasterization execution time (RET) for display commands that define images to be printed in each page strip of a page. The processor compares the RET for each page strip with a threshold value and rasterizes in the standard manner any page strip whose RET is equal to or less than the threshold value (while operating under the influence of the first clock frequency). When a complex page strip is found (whose RET exceeds the threshold), the variable frequency clock is controlled to generate a second higher frequency clock signal and to cause the processor to operate at a rate determined by the higher clock frequency so that display commands in the complex page strip are rasterized at higher speed.
    • 页面打印机包括用于产生至少两个时钟频率的可变频率时钟,一个高于另一个。 页面打印机包括用于存储页面处理过程的第一存储器和用于存储包括全页条带的数据的第二存储器。 处理器在第一时钟频率下与页面处理过程一起操作,并且导出用于定义要在页面的每个页面条中打印的图像的显示命令的光栅化执行时间(RET)。 处理器将每个页面条的RET与阈值进行比较,并以标准方式栅格其RET等于或小于阈值(同时在第一个时钟频率的影响下工作)的任何页面条。 当发现复杂的页面条(其RET超过阈值)时,控制可变频率时钟以产生第二较高频率时钟信号,并使处理器以由较高时钟频率确定的速率工作,使得显示命令 复杂的页面条以更高的速度进行光栅化。
