我国近年来从国外引进的一批微型计算机,其中某些外部设备不全,在使用中受到了一定的限制。另外,在利用微型机进行控制,数据处理等,有时只需要简单地打印某些最终结果和符号标志,但目前打字机,印字机等外设比主机的价格还昂贵。另一方面,我国还引进了一批带微型打印机的计算器。例如:VOESA 1871 PD 型计算器就是其中的一种。这种微型数字打印机具有价格便宜、小巧、打字清楚等优点,因此把计算器用的微型数字打印机,用于某些只要求打印数据的微型机处理系统,不能不说是一种捷径,具有一定的推广应用价值。
In recent years, a batch of microcomputers introduced from abroad in our country, some of which are incomplete, are subject to certain restrictions in use. In addition, the use of microcomputers for control, data processing, and sometimes only need to simply print some of the final results and symbolic signs, but at present typewriters, printers and other peripherals than the host of the price is expensive. On the other hand, China also introduced a number of calculators with micro-printers. For example: VOESA 1871 PD calculator is one of them. This miniature digital printer with the advantages of cheap, compact, typed, etc., so the calculator with a miniature digital printer for printing data only requires some micro-processing system, can not be said to be a shortcut, with a certain Promote the value of application.
