IBM Wheelwriter

Daisy wheel electronic typewriter by IBM

The Wheelwriter is a line of electronic typewriters that was manufactured by International Business Machines Corporation (IBM) from 1984 to 1991 and by Lexmark International (a spin-off of IBM) from 1991 to 2001. Typewriters in the Wheelwriter series use swappable daisy wheel cartridges to produce high-quality letterforms on the page via an ink ribbon and an impact printing head.
