Thank you all. Chopsaw, I was so used to print with Cute PDF with my Chief older version than I didn't even realize I could to use Chief save to PDF!
I just tried it and actually it works great. But the file big. As I mainly sent the files to my clients for their residential project, I don't need that extra quality.
I don,t know what happened with Cute PDF lately, but I will try the Bullzip driver mentioned by Ridge_Runner.
Thanks again to all of you for your answers!
