trouble installing epson 2400

Just recently received a new imac 24 for xmas and i'm trying to intall the epson 2400 which i was using on my pc laptop. I've tried downloading the latest drivers for intel based OS but when i try to find the printer there is no listing of the epson stylus pro 2400. I was able to install the cheaper epson 4600 with no issues. When I go to add printer it recognizes the printer as E and tells me that it's connected firewire, but thats it. Any suggestions would be welcome. Owen
