PDF 密碼的簡介
The standard security provided by PDF has two different passwords: user passwords and owner passwords. A PDF document may be protected by a password for opening (user password) and the document may also specify operations that should be restricted even when the document is decrypted: printing; copying text and graphics out of the document; modifying the document; and adding or modifying text notes (using owner password).
系統需求
Supported by Windows 98/ME/NT/2000/XP/2003/Vista/7/10 (and later) of both 32 and 64-bit.

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.
