The SmartSource Coupon Printer is a small Active X browser plug-in (or Mac applet) that enables you to print our coupons directly to your printer. It allows for high-quality coupons that will scan at the register. It also controls the number of coupons that can be printed in order to prevent fraud and protect the manufacturer. This is why retailers trust SmartSource coupons. Installation of the SmartSource Coupon Printer is required in order for our coupons to print.
