A true CMYK RIP will accept CMYK data as input (and usually RGB as well) 
and will not convert it to RGB and then again to CMYK internally like 
the Epson driver does. The CMYK data fed can go straight to the printer 
after a channel split or get an CMYK printer profile treatment in the 
RIP before it goes to the printer (proof printing).

QTR is a different specie altogether.
