A mirror printing algorithm and programming method were put forward by studying and anlyzing the instruction sets of HP series laser printers,which processed the dot data sent by computer′s HP laser jet driver to printers,to realize mirror printing on HP laser printers.

通过对HP激光打印机指令集的分析与研究,提出了在计算机中对HP Laser Jet驱动程序送往打印机的点阵数据进行镜像变换的算法和程序实现方法,实现HP系列激光打印机的镜像打印。
