I'm looking for a way to upload PDF articles and not have viewers download or print them. Based on my research, it's not possible because once a browser shows a PDF it's already been downloaded and a viewer can use the Print and Save command from the browser application. Another option is to turn my PDFs into JPGs or Flash, but that requires a lot of time because my PDF library is pretty extensive. Is there an online company that provide the service I'm looking for? Thanks!
