A typewriter is a mechanical or electromechanical machine for writing characters similar to those produced by printer’s movable type. A typewriter operates by means of keys that strike a ribbon to transmit ink or carbon impressions onto paper. Typically, a single character is printed on each key press. The machine prints characters by making ink impressions of type elements similar to the sorts used in movable type letterpress printing. At the end of the nineteenth century, the term typewriter was also applied to a person who used a typing machine.
