Hello all! I am wondering how to install the "coupon printer" from pages such as Red Plum. I want to print coupons wirelessly from my iPad and just bought a new AirPrint HP to allow me to do so. I only need to know how to install the coupon printer software which is required on coupon websites. I can't get the page to display which allows me to download and/or trying to install does nothing at all. Any help is appreciated!
