A teleprinter is an old machine that looks like a typewriter joined to a phone line. Someone types a message on a machine in one city, and your machine, far away, prints that message out on paper by itself, the keys moving with nobody sitting there. Before fax and email, this was how news agencies, offices, airports, police stations and armies sent written messages quickly over long distances. It is a British word; Americans usually said 'teletype' or 'teletypewriter'. You will now meet it almost only in history — in old films, in news programmes that use the clattering sound as a signal that something urgent is arriving, and in phrases like 'the news came in on the teleprinter'. There is one place it lives on: teleprinters were adapted as text phones for deaf users, and in Britain 'teleprinter' or 'textphone' can still refer to that.

電傳打字機、電報打字機。台灣舊新聞社、機場、軍方用的那種會自己喀喀喀打出字的機器；老一輩可能說「電傳機」。現在幾乎只在歷史或懷舊語境裡出現。
