    • A method of modulating a peak power requirement of an inkjet printhead is provided. The printhead comprises a plurality of first nozzles and a plurality of second nozzles supplied with a same colored ink. The first nozzles and second nozzles are configured in a plurality of sets, wherein each set of nozzles comprises one first nozzle and one corresponding second nozzle. Each nozzle in a set is configurable to print a dot of the ink onto a substantially same position on a print medium. The method comprises the steps of: (a) selecting a firing nozzle from at least one set of nozzles, the selection being on the basis of modulating the peak power requirement; and (b) printing a dot onto said print medium using said firing nozzle.
    • 提供一种调节喷墨打印头的峰值功率需求的方法。 打印头包括多个第一喷嘴和多个第二喷嘴,其供应相同的彩色油墨。 第一喷嘴和第二喷嘴被配置成多组,其中每组喷嘴包括一个第一喷嘴和一个对应的第二喷嘴。 一组中的每个喷嘴可配置为将墨水点打印到打印介质上的基本相同的位置上。 该方法包括以下步骤:(a)从至少一组喷嘴中选择点火喷嘴,所述选择是基于调制峰值功率要求; 和(b)使用所述点火喷嘴将点印刷到所述打印介质上。
