Linotypist
Linotype \Lin"o*type\, n. [See Line; Type.] (Print.)
A kind of typesetting machine which produces castings, each of which corresponds to a line of separate types. By pressing the keys of a keyboard like one on a typewriter, the matrices for one line are properly arranged; the entire line, or stereotype, or slug, is then cast and planed, and the matrices are returned to their proper places, the whole process being automatic.
The slug produced by the machine, or matter composed in such lines. -- Lin"o*typ`ist, n.
