Abstract
To reduce a memory area required to store bit-map data in a character output device in which bit-map data generated from outline data is stored for reuse. If font data corresponding to one character data read is from an input data RAM, then bit-map data is generated from the character data. If the vertical size of the bit-map data is 64 dots or longer than this, then the bit-map data is converted into run length data, which is stored in the font data RAM. If the vertical size of the bit-map data is less than 64 dots long, then the bit-map data is stored in the font data RAM.
