It seems that you've already set up and configured the print server using your PC. In theory, it should be as simple as using Printer Setup Utility to add an IP Printer, using the IP address assigned to the StinkSys print server (follow the instructions on Brad's first link). Make sure the Epson print drivers are already installed on your Mac.

Otherwise, I'd take the print server back to wherever you bought it and return it, pointing out how they never told you that StinkSys does not support Macs. There is absolutely no reason you can't use a Belkin printserver with your existing StinkSys router.
