Abstract
When a host computer transmits print data to a printer, the computer investigates the possibility of overrun per each band of band obtained by partitioning a page into bands. The host computer designates pre-rendering processing in regard to bands in which overrun is judged to be possible. Upon receiving the print data, the printer generates and compresses image data beforehand in regard to a band for which pre-rendering has been designated and stores the compressed image data. In case of a band for which pre-rendering has not been designated, the printer generates an intermediate code at a stage prior to the generation of image data from the print data. At the time of printing, image data is generated in one of two band buffers and image data is output from one band buffer. At this time the compressed image data is decompressed in case of a band for which pre-rendering has been designated, and image data is generated from an intermediate code in case of a band for which an intermediate code has been generated.
