Need help designing a network.

For my assignment, I am designing a network for one of the college building. I am trying to figure out how design the faculty office network.

What I have so far:

The faculty router is connected to the faculty file server and the faculty switch. The faculty switch connects to a Cisco phone, located in each office. Phones are also connected to the single computer in each room.

What I am trying to figure out:

How should I set up the printers? I was thinking of having 1 cheap printer in each office. Then creating a designated printing room with one computer and a 2 multifunction printers.

I'm still learning, so all advice is welcomed. Thanks in advance.
