Digital BW, The Print

This week end I installed QuadTone  RIP, Gimp-Print and Ghostscrip as 
instructed on Roy Harrington's website.  As of now I can not get the 
Epson 2200 cool and warm profiles to show up in the appropriate dialog 
box on the "Print" screen.

I have checked  (as root)  the path usr/share/cup/quadtone/2200 and the 
two text files show up there.  I named the printer "QUADTONE2200" per 
the instructions amd the two curve files have the printer name 
QUADTONE2200.

I can print both as a Gimp 2200 printer and as a QUADTONE2200 printer. 
I just can't select the two curves in when trying to use QuadTone RIP.

I have installed and uninstalled printers several time.  I am using the 
last version of Epson's driver which included the upgrade for roll 
page, borderless  printing etc.  Should I uninstall the "Epson 2200" 
printer?

As Yul Brenner sang in the King and I , 'tis a puzzlement".

Thank for any help you can give.
