Help connecting to Canon Pixma MX490

We just set up our printer the other night, but we've had it for a while. It was taken out of the box before we moved houses and we've lost the manual to it. I was able to connect to the Wi-Fi router using an online manual, but now I'm lost.

Is there something that needs to be downloaded onto my computer or our phones in order to use it? I've tried printing a page, but it doesn't pop up. I've never owned a wireless printer so I'm pretty ignorant about this whole thing lol. Please help and thank you in advance.
