How do I set a printer to serve 2 computers through a router?

[MSwhip]

I have a SMC Gateway Router and 2 computers connected to it with RJ-45 cable. They are (1 iMac + 1 PC) 150 feet apart both computers are wired to the router. I also have a Canon Pixma MP 560 Multifunction Inkjet printer that has the capability to be connected both wired and wireless. Right now it is only connected to the iMac via a USB connection as all 3 (router, iMac and printer) are on the same workstation.
I would like a detailed explanation as to how to connect the printer so it could also support the 2nd computer a Windows PC which is located on the floor below. Can I do that through the wired router too?
If not possible, I also have the capability to connect wirelessly although I would prefer to use the wired connnections.

The PC has a Belkin USB 2.0 Network Adapter for wireless connection; both SMC Router and Belkin USB adapter are 902.11 N capable

I would appreciate receiving help preferably detailed and in layman terms as I am not too versed on these tech issues.


Thank you kindly
