Print data of each page sequentially sent from a host computer and second print data converted from registered first print data and stored in a memory are developed on the memory to generate a print image under the control of CPU. An overlap print by a printing unit is controlled in accordance with the generated print image. Even if the print style of input print data of each page changes, optimum second print data can be generated in a short time without giving a load on memory resources. Therefore, a print process time of formatted print data such as forms can be shortened and a desired overlay print can be performed efficiently.

Print control apparatus, print control method, storage medium, and computer readable program performing a form overlay process

An output control apparatus which delivers a character pattern in accordance with a character generating request from a host computer and which selects one of a plurality of fonts in accordance with data designated by the host computer, comprising means of selecting a font of characters to be outputted in accordance with an attribute thereof, memory means for storing therein a plurality of font data and a plurality of font scalers, means for setting degrees of priority of the plurality of font scalers, and means for selecting a font of characters to be outputted in accordance with a degree of priority set by the setting means at the time when said font of characters to be outputted is selected.

Apparatus for and method of controlling output

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.
