ABSTRACT:
It is an object of the invention to reduce an amount of data which is supplied to a character outputting process and to execute the character outputting process at a high speed. On the basis of extra-character registration information, whether bit map data is compressed or not is judged. When the bit map data is not compressed, an extra character is registered into a predetermined area of a storage. When compressing, in accordance with a compression method which is designated by extra-character registration information, the relevant compression method is selected and the bit map data is compressed. Data of the compressed extra character is registered into a predetermined area of the storage. By performing a character output by using optimum font data and scaler every character unit or character set, the data amount can be reduced, the process can be executed at a high speed, and a high-quality output can be performed.
