Claim:
An image processing device comprising: a plurality of print processors for different colors, each of the plurality of print processors performing printing of a corresponding color onto a recording medium; a plurality of first conversion sections provided for each of the plurality of print processors, each of the plurality of first conversion sections converting print data described in page description language into raster image data, and outputting the converted raster image data to the corresponding print processor; a second conversion section that converts the print data into raster image data and outputs the converted raster image data to any of the plurality of print processors; and a controller that selectively performs a first control that causes the plurality of first conversion sections to convert the print data that has been input to the device, or a second control that causes the plurality of first conversion sections and the second conversion section to convert the input print data; wherein the controller performs the second control in a case in which a time period that is expected to be needed in order to carry out conversion of all of a plurality of pages included in the print data when carrying out the second control, is shorter than a time period that is expected to be needed in order to carry out conversion of all of the plurality of pages included in the print data when carrying out the first control.
