Wont connect to my printer

Everything had worked flawlessly with this printer until it was time to test the mobile printing. The app simply refuses to recognize my printer. It has been in searching mode for hours. Ive tried closing and opening the app as well as deleting and redownloading the app to no avail. Not cool to offer and advertise something that doesnt work.
