It is actually very simple, you will first need to download the coupons.com app from the App store on your iPhone or iPad, this is FREE to download.
You will also need to make sure that you iPhone and iPad are connected to your local WiFi network so it can detect the printer.
I have this HP Photosmart 5550 Wireless 3 in 1 printer – most HP wireless printers can be detected by your iPhone. I had to install my printer driver on my computer and make sure I put it on my Wireless Network, make sure my home computer was on, and then make sure that my HP printer’s wireless feature was on. I had issues with this at first, but I went to my printer and I didn’t have the Wireless button pushed on my printer.
Now when you go to your coupons.com App you can select the coupons that you want, click on view list, and then print. Your iPhone or iPad should automatically detect your printer, and you can send the coupons right to your printer!
So hopefully this helped you successfully print coupons from your iPhone or iPad!
