QTR-Quadtone RIP

I'm new to digital printing, but not new to photography.  I've been 
using the Epson R2400 printer for several weeks with the Epson 
driver.  I down-loaded version 2.3.0 of the QTR.  There are no curves 
for the R2400.  Did I load the application incorrectly, or are curves 
not available for my printer?  Thanks....
