20世纪五六十年代,随着计算机的发展,经计算机处理和生成的各种数据、资料也越来越多,很多时候需要呈现在纸张等传统介质上。过去,手写、印刷或打字,是让纸张承载信息的传统手段,而为了让计算机数据也能呈现在纸上,专用的打印设备也就应运而生了。 In the 1950s and 1960s, with the development of computers, various data processed and generated by computers were used more and more, and most of the time they needed to be presented on traditional media such as paper. In the past, handwriting, printing, or typing was the traditional way of letting paper carry information, and a dedicated printing device came into being to make computer data available on paper as well.
