Digital BW, The Print

Dear forum user,

I have an Epson 4000 and until now have used QTR for printing b&w.

I would like to test and use other papers than the ones for which a 
profile is provided with QTR. 

For the same price I may purchase the Imageprint Rip or the Printfix 
Pro solution. The simpliest solution seems to me to buy Imageprint 
(though it is dedicated only to the Epson 4000). 

What would be your advice between the two solutions for best B&W prints 
if I want to print on other papers than Hahnemuhle Rag or Epson papers?

Thank you for your advice.
