Abstract:
1. A printing apparatus that forms an image generated by analyzing document image data including a plurality of pages on a conveyed sheet, the printing apparatus comprising: an estimation unit configured to analyze document image data of each page and estimate a printing time of each page by adding an intermediate data generation time for generating intermediate data and a rendering time for rendering the generated intermediate data; a determination unit configured to determine whether the printing time of each page estimated by the estimation unit keeps up with a timing at which an image needs to be formed on a sheet conveyed for each page; a discrimination unit configured to, if it is determined that the printing time does not keep up with the timing at which the image needs to be formed, determine whether an idle time for pausing rendering between pages is present by comparing the intermediate data generation time and the rendering time; and a changing unit configured to, if it is determined that the idle time is present, change an optimization level for determining whether to perform processing on a particular object in the document image data during rendering or to perform the processing during intermediate data generation.
