打印机作为计算机的主要外部设备,它的地位仅次于显示器。我们在电脑上编辑的文章、绘制的图画最终都要通过打印机保留到纸上。打印机一般分为击打式、喷墨式、激光印字式几类。击打式打印机是打印头上的打印针打击色带并在纸上印出圆点,再由圆点组成字或图形。因此,击打式打印机打印出的字或图比较粗糙,并且,打印机在工作时噪声比较大。它的优点是各种纸张都可以使用,并且可以在打字腊纸上打印,适合于学校使用。如LQ-1600K。 Printer as the main external computer equipment, its status second only to the monitor. The articles we edit on the computer, the drawings we draw are all ultimately left on the paper through the printer. Printers generally divided into the hit, inkjet, laser printing several types. Impact printers are print pins on printheads that strike the ribbon and print dots on the paper, which are then dotted or dotted with dots. As a result, the typeface or plot printed by the impact printer is rough, and the printer is noisy at work. Its advantage is that all kinds of paper can be used, and can print on typing wax paper, suitable for school use. Such as LQ-1600K.
