Abstract
A fast-output image processing method and apparatus which employ an outline font. A page printer embodying the present invention stores form data received from a host computer into a RAM before printing output. Upon mapping of the input code data, examination is made as to whether the necessary pattern is stored in a cache memory or not, and if it is not stored, the pattern is registered. As for form data, similar pattern registration is performed to a cache memory for form character. The pattern registration is repeated until data for one page is mapped. In the case where the respective cache memories are full, the pattern of the lowest access frequency among registered patterns is deleted, thus realizing effective use of cache memories.
