单选题 Ink-jet printer belongs to nonimpact printers in which the characters are formed by projecting particles or droplets of ink on to paper. (71) printer is also a n0nimpact printer in which the characters are produced by applying hot elements to heat-sensitive paper directly or by melting ink from a (72) on to plain paper. Electrostatic printer creates an electrostatic latent image, which is then made visible by a toner and transferred and fixed on paper. An electrostatic printer may be used in some instances as a (73) . Laser printer creates, by means of a laser beam directed on a (74) surface, a latent image which is then made visible by a toner and transferred and fixed on paper.

喷墨打印机属于非击打式打印机，其中字符由投射在纸上的印墨微粒或微滴形成。热敏打印机也是一种非击打式打印机，其中字符通过将热素直接加在热敏纸上或将色带上的印墨熔化到普通纸上产生。静电打印机产生某种静电潜像，然后以上色剂显现出来并转移、固定到纸上。静电打印机在某些情况下可用作绘图机。激光打印机通过指向光敏表面的激光束产生一种潜像，然后以上色剂使之可见并转移、固定到纸上。磁像打印机通过磁头在金属鼓上运行来产生一种潜像，然后以上色剂使之可见并转移、固定在纸上。计算机输出微胶卷(COM)打印机在摄影胶卷上产生每页的缩微影像。
