Wireless printer not connecting to my iphone?

So I purchased this canon wireless printer, Pixma Mg2922 and I was planning to print out documents through my I phone. I set it all up and everything, got the app, was even able to print out a picture when I finished setting it up and connecting my Iphone 5c to the printer. I don't use my printer for a few weeks and forgot how I set it up, but I don't want to set it all up, all over again. I just want to print out some papers and I go to print and connect my printer but it said "no air printers found". Even though I connected my phone to the printers Wi-Fi, and the Wi-Fi light was on and blinking on the printer. How do I connect my printer with my iphone properly and is there another way to print documents, because I have a windows rt device too.

Is it possible to but dial someone with an iPhone?

I mean I'm sure it's possible but like once a week couple times a month. It's my sister in law's husband, I usually let it ring and go to voicemail but voicemails are never left. I told my husband they called and he said but dial. But the iPhone's usually shut off don't they and likely you have to scroll through contacts to choose I would think I've never but dialed with mine. So is that likely?
