Digital BW, The Print

I am using windows XP and have recently downloaded Quadtonerip version 
2.1.8. I have an Epson 2200 printer.Each time I try to print, I receive
the above noted message that states that there is a fatal error- PPD 
environment not set. I scanned any previous messages but have not found 
the solution for the XP environment. Any help would be most appreciated.
