Connecting wireless printer to secure school server

I'm trying to connect my laptop to my wireless printer, but I have to use the school wifi to do it. It's a protected network that requires me to log in with a username and password. I cannot use a personal router because they are not allowed, and when I try to connect the printer itself to the wifi I need to input both my username and password, but only a spot for the password shows up. What should I do here?
