How to connect one printer into two Multipoint server 2012

good pm. I have a problem on configuring printer in multipoint server 2012. pls help me.

I installed printer in the main server and its perfectly working with the main server and on its client pc, i've already shared the printer to the network and the sub server has an access on it and can print documents, but the client pc on sub server can’t access the shared printer on the main server. What should I do?
