QTR-Quadtone RIP

hello all,

I was introduced to QDR by a link in Photo.net. I was pleased when I 
went to the website. If I understand correctly my printer (R1800) is 
in the R800 family and would have to choose that printer when setting 
up. correct? and I can only use a USB connection to the printer 
(running OSX 10.4.9).

I would like to buy the program but am nervous if it will work with my 
printer. I got it 3 days ago and currently connection through 
firewire. 

Oh and is there a large learning curve with this software?

thank you for your time
