Ok, Do I have to download adobe acrobat to save my documents as PDF. I know that I can do it through File>Print>Save as PDF and open it thorugh Preview. I did that and had send a document to my friend who uses a PC. and he said that it was all blank. there was nothing in it. I made something on comic life and did the above steps and he could not see anything. So do I need to download Acrobat.
