Laptop won't connect to printer?

We have a wireless Epson XP-225 printer and scanner, and up until a couple of days ago we were able to print things off no problem. Then we had an issue with our laptop (it's a Lenovo laptop incase anyone was wondering) and had to reset it, but even then it worked fine until a few days ago when I went to print something off and the laptop can't even find the printer.

The printer is definitely connected to our Wi-Fi and so is the laptop, so I'm just wondering what I can do to fix the issue? I've tried adding the printer again but it comes up with it trying to find the TCP/IP address thing and it just takes forever so I just exit off it. I've removed the printer but it still can't find it, and that's where I'm up to today - with a removed printer and no way of trying to find it.

I should note that I've tried putting the disc to set up the printer again but I just don't feel the need to considering it's already been set up. And, although it says it will automatically update the screen to the next set of instructions once connected to the Wi-Fi, it never does. Even when it's clearly connected to the Wi-Fi. However, I feel like this might be because the signal isn't that strong as that's what happened when we first set it up so we had to use a Wi-Fi adapter. I can't find it at the moment though, but I just want a second opinion, so could it be that?

Sorry for the long description, I'm just in dire need to print my assignments off… Please Help!

Hmm
