"Add Devices" never finds the device I want it to

[Dadstar0410]

I got a new wireless printer for my room and for college. I set it up under the same WiFi network as my Surface, and it connect fine to the WiFi. With my Surface I go to "Add A Device" in PC Settings. I press the + and wait. No devices found. EVER. What's the problem, and how can it get fixed?
