 Hello

I have the latest version, I want to protect pdf files from selection then copying (paste) and also from any modification. 
Menu option/format pdf/security tab

I select

1°copying text and images

2°modifying document

3°modifying comments

but when printing i can easily select any part of text and copy it anywhere

Could please help (i am on windows 7)

Thank you in advance
