    have read the notes mentioning that this is not a can NOT copy/print
    the PDF how-to....but rather how-to make it more difficult for _some_
    folks to print/copy the PDF..

    reminds me of my dad's wise words:
    *Locks are only to keep honest people out.*

    (because a door lock (for example) is *no* barrier to _some_ folks,
    and neither will this how-to keep a determined, suitably knowledgeable
    and equipped individual from misusing the PDF's information..)

    A lock is only as secure as the guy with the key..

    It is nothing. Certainly not a protection.

    Merely a *request* that the document may not be copied or printed. It only
    works if the viewer (i.e. Acrobat Reader) reads and honours these requests.

    Lots of PDF readers don't bother with it, in my experience.

    Want to remove those silly flags ?
    Open the PDF with Document Viewer, Okular or most of the other PDF viewers
    you can easily find.

    Print to a new PDF.
    End of "protection" (annoyance, really).



    We don't honour DVD encryption that tries to refrain us from viewing it's
    contents on our preferred device.

    So why would we accept such a limit for reading a document?

    If I am given a document to read, why would I be forced to do so on a
    monitor, rather than on paper, or from a file format supported on a device
    that has no PDF capability?

    Such a feature is needed wherever you access restricted documentation; but
    in such places they also control what software you can have on the computers.

    You can not install anything yourself, so these things work, as there is no
    software available to break the controls.

    Forget about plugging an usb memory stick: the bus may have no wires
    connected, and the box is locked and alarmed.

    There are such things as fonts designed so that OCR do not work, too.


    Needles to say, manage to bypass the restrictions and you are fired.

    So that you do not take private patient data and sell it to the press, for
    instance.

    That is the good case.

    .... so that you do no take confidentiel criminal information and give it to
    the press, is another instance.

    In our case it means you don't take a controlled copy of a document and create your own printouts. We have a document that is on every ward and all copies are version controlled and kept up to date. This way people have access to it on their pc without being able to print and keep a copy in their office.

    It is interesting to see that this how-to created a bit of a discussion.. Been a interesting read so far.. Thanks everyone!
