Patent ID: 7061649

Claim:
A page data processor for processing page data described in a page description language, comprising: a) a rasterization processing element for rasterizing said page data and generating output data output-processible by an output device; b) a data transmission element for transmitting said output data to said output device; c) a first time calculation element for calculating a rasterization processing time necessary for generating said output data; d) a second time calculation element for calculating an output processing time required by said output device for output-processing said output data; and e) an output start time calculation element for calculating an output start time for starting outputting said output data from said output device on the basis of the current time, said rasterization processing time and said output processing time, wherein said rasterization processing element further comprises a data division element, said data division element divides said output data into a plurality of output files by generating one of said output files every time said page data rasterized reaches a prescribed data size, and said data transmission element transmits said output data to said output device for each of said plurality of output files at said output start time.
