A mailing form, including an upper sheet of material adhesively fastened to a lower sheet, is configured for the printing of information on a single side during passage of the form through a non-impact printer. At a first end of the form, the upper and lower sheets are fastened together permanently, forming a pocket to be used as a return envelope. The portion of the upper sheet which extends away from this pocket is divided into an inner flap, on which information is printed, and an outer flap, which is temporarily fastened to the lower sheet in order to protect an adhesive pattern during the printing process. After the printing process, the outer flap is removed and discarded, the inner flap is folded along lines provided for folding, and the lower sheet is folded on itself to enclose the inner flap. As the adhesive pattern holds the lower sheet shut in this position, address and return address information printed on the inner flap is visible through apertures in the lower sheet, which forms an envelope. After receiving this envelope, the recipient separates the pocket forming a return envelope from the rest of the materials. A part of the inner flap may be returned in this return envelope, together with a check or other remittance as desired. The address and return address has been printed on this envelope during the printing step. Before the return envelope is mailed it is sealed using a flap with remoistenable adhesive.
