最終目的是要PDF可開啟看內容但不可列印及另存新檔.

This might not be possible - once you allow users to read the file, the content of the file is actually stored in the computer memory. "Save as" function basically save whatever in the memory to a new file. I don't think you can control "Save As" once you allow "read" to the target pdf file.
