compositor

A person who sets type; a typesetter.

Thus, when he drew up instructions in lawyer language […] his clerks […] understood him very well. If he had written a love letter, or a farce, or a ballade, or a story, no one, either clerks, or friends, or compositors, would have understood anything but a word here and a word there.

All Spaniards, we discovered, knew two English expressions. One was 'O.K., baby', the other was a word used by the Barcelona whores in their dealings with English sailors, and I am afraid the compositors would not print it.

One who, or that which, composes or sets in order.

I work as an image compositor.

A system that puts images together in a buffer (such as individual windows on a desktop) to generate a final display image.
