PRINTING SYSTEM

PROBLEM TO BE SOLVED: To easily select a size of a paper sheet and post-processing for a paper sheet enclosed in a windowed envelope, and also to determine an area where printing can be performed at a position which can be surely seen from a window, in a printing system in which a printed matter printed by a printer capable of accepting a print job is subjected to cutting and folding processing by a post-processing device. SOLUTION: A difference in size is computed from an envelope size, a window position, and size information on a body to be enclosed, and the area where the information of the enclosed paper can be seen from the window is printed is determined so that even if the form having been enclosed is smaller than the envelope size and moves in the envelope, the information to be seen from the window is printed in the area which is surely seen from the window. Alternatively, the folding position and cutting amount of the post-processing are determined such that the enclosed paper sheet is post-processed to nearly the same size as the envelope size so that the enclosed paper sheet does not move in the envelope.
