Digital BW, The Print

ok I'm stupid.

I downloaded qtr, but I can't find any instructions or manuals... can anyone pass on a clue 
to how to get it to work. I've searched the forum to no avail. It seems to have loaded onto 
my g5 ok (it's in the ppd folder). I've searched roy's site and there's a 'program and profile 
installation' guide, but nothing on how to get it up and running

cheers

steve
