ABSTRACT:
There is disclosed a print data processing apparatus for an image forming apparatus for receiving print data from an external unit, converting the received print data into dot image data at every one of bands defined by dividing an image area of one page, and outputting the dot image data to a printer so as to form all the image of one page corresponding to the print data on a piece of printing paper. In the print data processing apparatus, print data received from the external unit are sequentially analyzed and converted into intermediate data, and the converted intermediate data are stored in a first storage unit. Thereafter, an edit controller judges which band the intermediate data stored in the first storage unit belong to, and registers judged band information of the intermediate data in a band table of a further storage unit. The intermediate data are developed into dot image data every band referring to the band information registered in the band table, and the developed dot image data are stored in a second storage unit. Finally, the dot image data stored in the second storage unit are outputted to the printer in order to print the image thereof on a piece of printing paper.
