teletype (n.)

before vowels tel-, word-forming element meaning "far, far off, operating over distance" (also, since c. 1940, "television"), from Greek tele "far off, afar, at or to a distance," related to teleos (genitive telos) "end, goal, completion, result," from PIE root *kwel- (2) "far" in space or time.

in the mechanical sense, 1868, from type (n.) + writer. Related: Type-write (v.) "print by means of a typewriter;" type-written (1882). Slang office-piano "typewriter" is by 1942.

It is the advantage of the typewriter that, due to its rigidity and its space precisions, it can, for a poet, indicate exactly the breath, the pauses, the suspensions even of syllables, the juxtapositions even of parts of phrases, which he intends. For the first time the poet has the stave and the bar a musician has had. For the first time he can, without the convention of rime and meter, record the listening he has done to his own speech and by that one act indicate how he would want any reader, silently or otherwise, to voice his work. [Charles Olson, "Projective Verse," 1950]
