Microsoft Windows 10 (32-bit)

I got a new router (from Verizon to T Mobile). My printer is now offline. How do I connect my printer to my new router via my laptop - Settings - Network and Internet - WiFi? Its asking for Network Security Key info under 4155 printer. I cannot find Network Security Key info on my router and all the info I put in, does not work.

Thank you.
