Network Printer on Mac

I have an Epson SX435 printer that has been on my home network for some time and I have been able to print from iMac.

Recently I installed a new hub, connected my PC, daughters macbook, Mac and printer to this network.

Since then I cannot print or see the printer when trying to add it on my Mac - works fine from PC and Macbook.

I have tried using IP address as well and it says it cannot find software.

Any help appreciated!!!
