An output apparatus and method include a character pattern memory for storing a character pattern, a screen pattern memory for storing a screen pattern to be synthesized with the character pattern stored in the character pattern memory, a synthesizer for synthesizing the character pattern stored in the character pattern memory and the screen pattern stored in the screen pattern memory, and a main controller for enlarging/reducing only the character pattern stored in the character pattern memory and synthesizing the enlarged/reduced character pattern with the screen pattern stored in the screen pattern memory when a pattern synthesized by the synthesizer is to be enlarged/reduced.
