Epson f6000

[Ceredford]

Hi, I have an epson SC F6000. I currently lease Shiraz carbon RIP.
id rather not have to spend money on RIP software. Can I print pdfs directly from my iMac OS X EL Capitan to the epson via USB cable? I went onto epson website and downloaded the driver and installed this. However when I go to add the printer to my print list i cant seem to find the driver in the "use" field drowndown box.

Can anyone advise please?

Thanks
