PURPOSE: To develop a font with high quality at high speed, by providing a high-speed temporary memory device storing a dot-font form font called a font cash.
CONSTITUTION: When a communication controller 101 receives a character output command, a main controller 102 analizes the command and requests a dot form font of a predetermined font to a font data controller 106. The font data controller 106 checks whether or not the dot form font is stored in a font cash 117. If it is stored, the dot font is returned to the source of the request as the result. If not stored, the font data controller 106 determines a font for use among font data 108W111. A font converter 112 converts the designated font to a dot font form, stores it in an area of the font cash 117, and returns the dot form font to the source of the request as the result. The main controller 102 transfers the dot form font to a specified area of an image recorder 103. A printing controller 104 actually performs printing with use of the data stored in the image recorder 103.
