QTR-Quadtone RIP

Hello,

I just downloaded and am trying out the RIP. My question is, in the driver settings (under OS 
X), I have two options in the pulldown - "QuadTone RIP" and "Printer Features". I understand 
the setup for "Quadtone RIP" but I'm unsure if I need to do anything under the "Printer 
Features" settings?

Basically, under "Printer Features", I'm given the option for different media types (seem 
sdefaulted to "Matte Paper", but have a number of options for different paper types, including 
various photo papers, Ilford papers, etc.). Do I need to do anything here?

Any advice would be appreciated!
Regards,
Kristin.
