“复印机” 或 “复印机” 是一种可将文档及影像快捷及廉宜地复印到纸上的仪器，由全录在1960年代开发，在随后的20年间逐渐取代碳纸复印技术、油印及其他复印机。它的普及应用，是令到在数码革命初期曾被倡议的无纸办公室仍无法实现的原因之一。

复印机在商业、教育及政府机构中皆被广泛应用。不少人曾经估计，在越来越多人以数码技术制作文档内容下，复印机会逐渐息微，亦会减少依赖纸张作传递文档之用，但毫无疑问复印机在复制文档这种简单工作上，确实比电脑更方便。

A photocopier (also known as a copier or copy machine) is a machine that makes paper copies of documents and other visual images quickly and cheaply. Most current photocopiers use a technology called xerography, a dry process that uses electrostatic charges on a light sensitive photoreceptor to first attract and then transfer toner particles (a powder) onto paper in the form of an image. Heat, pressure or a combination of both is then used to fuse the toner onto the paper. (Copiers can also use other technologies such as ink jet, but xerography is standard for office copying.)
