Early user terminals connected to computers were, like the Flexowriter, electromechanical [[teleprinter]]s/teletypewriters (TeleTYpewriter, TTY), such as the [[Teletype Model&nbsp;33]], originally used for [[telegraphy]]; early Teletypes were typically configured as [[Teletype Corporation#KSR|Keyboard Send-Receive]] (KSR) or [[Teletype Corporation#ASR|Automatic Send-Receive]] (ASR). Some terminals, such as the ASR Teletype models, included a [[paper tape]] reader and punch which could record output such as a program listing. The data on the tape could be re-entered into the computer using the tape reader on the teletype, or printed to paper. Teletypes used the [[Digital current loop interface|current loop]] interface that was already used in telegraphy. A less expensive [[Teletype Corporation#RO|Read Only]] (RO) configuration was available for the Teletype.

Custom-designs keyboard/printer terminals that came later included the [[IBM 2741]] (1965)<ref>{{cite web |url=https://www.ibm.com/ibm/history/exhibits/dpd50/dpd50_chronology3.html |title=DPD chronology |website=[[IBM]] |date=January 23, 2003 |quote=1965 ...

The DECwriter was the last major printing-terminal product. It faded away after 1980 under pressure from video display units (VDUs), with the last revision (the DECwriter IV of 1982) abandoning the classic teletypewriter form for one more resembling a desktop printer.
