Print controlling method and apparatus using a plurality of processors

Drawing processes and print processes for respective pages are performed in accordance with print commands by a plurality of processors. The print commands over the plurality of pages are stored in a command buffer. In successively allotting the drawing processes for the different pages to the different processors, a chain of the print commands ranging over the plurality of pages is fetched from the command buffer, whereupon imaginary drawings for setting drawing attribute parameters of the respective pages are executed sequentially without executing the respective real drawings. The real drawings are executed for the pages having completed the imaginary drawing, by the respectively assigned processors in parallel on the basis of the print command chain and in accordance with the set drawing attribute parameters set in the imaginary drawings.
