If a presentation mode to print a presentation material and a distribution material is selected and the number of copies of printing of the distribution material is set, a printing job is issued from a computer to a printer in accordance with the setting. Thus, on the basis of printing data included in the issued printing job, the printer prints the data of each of plural pages on a one transparent recording sheet in color as the presentation material, and further prints the data of predetermined number of pages in monochrome for the number of copies of printing set so that the data of the predetermined number of pages are put on a one plane paper as the distribution material.
