How rare, I was only looking into this myself on sunday. I ended up downloading MyPDFCreator. It does the job, but annoyingly I can't get it to stop loading on startup.
It is the best one I have found so far, and I've tried about 10 different products when rolling out a citrix environment, and this was the least intrusive, and it "just works" which is always good.
NOTE : If for some reason msconfig won't load (I don't know why this happens on some machines but it does) then you can use the Tools icon in ccleaner to remove startup items in the same way you would untick them in msconfig.
Although my copy of office is and has everything in the wrong place compared to what I'm used to, it does do useful things. I have got pdf creator buried somewhere in my utilities folder, but I don't think I've ever used it, I dislike pdf and generally avoid it.
