Check Security: a practical guide
A PDF can refuse to print for two very different reasons: it may need a password to open, or it may open fine but carry permission flags that block printing and copying. Guessing between the two wastes time. This check reads the file security dictionary and lists what it finds, including the encryption method, without asking for the password and without altering the document.
