Digital BW, The Print

I'm going to install this and try it out tonight.  Anything special I 
should know re: installation or use? I ask because I'm not at all 
familiar with Gimp Print, and want to make sure I put all the pieces 
together correctly so I can properly evaluate the RIP.  I'm running 
OS 10.2.4 on a mac G4 w. an Epson 2200.
