Hello, I’m Nathan, and I’ll be assisting you today.
Sorry to hear that you’re having trouble with this but I’ll do my best to help you out.
The WPS button is not on the printer itself.
WPS is a connection method you'd choose from within the wireless setup menu,
you'd then go to your wifi router, and press the WPS button on it, which is usually on the front near the lights/indicators. Many wifi routers don't support that feature though because it is not considered as secure as using a password.
If you can't find it, or your router doesn't have it, then you'd go through the guided wifi setup on the printer and simply choose your network name from the list it finds, and type in your wifi password.
Do you need more help with this?
