AFAIK, disabling printing is the main purpose - a lot of journals that post online articles seem to prefer this, so that people will still pay for offprints of articles. Except of course, we usually don't. I hear that KDE 3.0 will have support for cut and paste in the PDF viewer, so that would screw that one up anyway. Let's face it, if someone really wanted to copy/edit/print and encrypted PDF file that much, they could view it, print out a screen shot and scan it into an OCR. Or just type it out by hand. Robin
