First document/image data is printed onto a sequence of sheets that includes sheets of a given size, and sheet(s) of a size that in at least one dimension is larger than the sheets of the given size. At the same time the first document/image data is being printed, second document/image data, i.e., foldout data, is printed onto the outer margin, i.e., a foldout portion, of the sheet(s) of the larger size. The larger-size, foldout sheet(s) is then folded so as to be creased near its overlap with the given-size sheets, and is collated into the sequence of the given-size sheets to form a bundle that is then bound. Thereafter trimming to size the non-bound edge(s) of the bundle slices away the crease in the foldout sheet, leaving the foldout cut-away as an insert tucked into the booklet.
