A typewriter is a mechanical or electromechanical machine for
writing in characters similar to those produced by printer's
type by means of keyboard-operated types striking a ribbon to
transfer ink or carbon impressions onto the paper. Typically one
character is printed for keypress, and the machine prints the
characters by making ink impressions of type elements similar to
the sorts used in movable type letterpress printing. After their
invention in the 1860s, typewriters quickly became indispensable
tools for practically all writing other than personal
correspondence. They were widely used by professional writers,
in offices, and for business correspondence in private homes. By
the end of the 1980s, word processors and personal computers had
largely displaced typewriters in most of these uses in the
Western world, but as of the 2010s the typewriter is still
prominent in many parts of the world including India.  Notable
typewriter manufacturer companies have included E. Remington and
Sons, IBM, Imperial Type
