Most of the time it works fine. When it doesn't, it usually has something to do with the print quality (DPI) of the PDF writer. This is found under Print-Properties(of the PDF writer)-Advanced-Print Quality. The two common occurences are:
Arcs are looking squared; set the DPI up (try 600).
The final print has streaks, blotches and/or boxes; set the DPI lower, like 300 DPI.
CutePDF is free and seems to work fine, although not better or worse than any others I've tried.
