    Owner/master passwords can be used to protect PDF files from printing, editing, change, and copying. With an owner password, users can get full access to the PDF file. This means if printing was disabled, you need to use owner passwords to print the PDF files. The second type is the user/open password. If you want to read an open password protected PDF file, you need to have an open password.
