To print from an iOS device, you need an AirPrint capable printer. The mx 870 is not AirPrint capable as far as I know.
There are some glitchy apps out there that can allow you to print from an iPad to a non AirPrint capable printer. The best is prontopia, which will allow you to print through a Mac computer. However, the best way to print from an iOS device is to use an AirPrint capable printer

Welcome to Apple Support Communities. We're all users here.
First, Canon has a free app designed for photo printing, iEasy Photo Print (iEPP).
If you also have a Mac running OS X 10.6 or newer, HandyPrint (formerly known as AirPrint Activator) from netputing.com might work for you. http://www.netputing.com/handyprint/
The Mac needs to be on and running the app in order to print. I used it for a time with several non AirPrint printers, both wired and wireless, connected to my Mac.
Because it is a Mac OS X app, rather than an iOS iPad/iPhone app, it DOES work with most iPad and iPhone apps seamlessly. (I won't say 'ALL' apps, because I only used it with a few dozen, and there are over 800,000 iOS apps out there.) You don't need to save your work and open another app in order to print.
HandyPrint is donationware. Download it and give it a try for up to 14 days.
If it works for you, great, you are asked to make a small donation.
If not, it costs nothing to find out.
