I just purchased a new printer, an EPSON XP-400. I started printing after I connected to my WIFI, and then all of a sudden it said it could not connect. I believe it's becasue the computer has a different IP address than the printer. Can two devices share the same IP address? Not sure how to fix this. Please help!

No such thing. Each device on an IP network MUST have different IPs. It's possible that your printer has "changed" IPs and if your computer was set to print to the original IP, that will no longer work. If that's the case, you need to assign a "static" IP address (one that doesn't change) to the printer so that it'll always be available at the same address. If this is a home network, use a high IP (something like 192.168.x.200) for the printer so that you don't accidentally overlap a static address with a dynamic one (one issued by your router) to any device that connects to the network.
Some newer printers that can do Bonjour protocol support don't need to be on static addresses since the bonjour name is what the mac is looking for to print to it, but it's still suggested that any and all IP based printers should be assigned static addresses if you want to do it the right way.
How do I share an IP address with EPSON XP-400?
