I remember I visited a website in which I could neither download nor print the document. This was disabled by the owner. I don't know how!
Regards,
I do not know of any way that we can support that.
Generally, preventing certain operations with PDF files requires special security features that require you to produce the file with Adobe Professional or the equivalent. In other words, what you observed was more likely related to how the PDFs were *produced* rather than the means to view them.
I know this because I have personally produced and worked with encrypted and high-security PDF files produced via Adobe Professional in the FDA-regulated space.
As we do not generally produce the PDF files you are providing for download, there really is nothing we can do about preventing how they are used.
