激光打印机都是以激光束来扫描感光元件成像的吗?答案当然是否定的。在彩色激光打印机中还存在一个分支,它们是以LED光学元件来扫描感光元件成像的,如果称之为“彩色LED打印机”似乎更为准确。
Is the laser printer scanning the sensor with a laser beam? The answer is of course no. There is also a branch in color laser printers, which image the sensor with LED optics, which seems to be more accurate if it is called a “color LED printer.”
