PDF file filtering (with /without password protection)

Recommended Posts

I need to control if a PDf file have a password protection to avoid a process that send it   to a printer .

If a print automatically a PDF protected file the process hangs up without response and i have no olg o control to kill the print correctly.

There is a simple method for doing this ?

Actually I print with the library _filePrint and even with my application .

Thanks a lot .
