Connecting to Epson Aculaser C900 via Belkin wireless printer server

I am new to Macs and have a wireless network setup for my Windows Desktop. I just got a wireless print server to which I connected my Epson Aculaser C900. The windows pc is printing to this effortlessly. I have tried (all through the weekend) to connect my imac G5 to it with all IP details etc but it's just not working. The best I am getting is 'printer busy, will retry' or someone as odd. Cant find the printer driver in the list dropping down in IPP setup. Can anyone help?
