    What makes you think clients would allow you to prevent them from printing the screen if they want so? – Oriol Dec 08 '16 at 07:00
  • There are few times when you should be doing anything but *optimizing for* the use of printscreen. Someone has found your content valuable enough that they want a hard copy; that's a compliment. – gyre Dec 08 '16 at 08:53

There are keystrokes you can't capture on many operating system/browser combinations. PrintScreen is very, very likely to be one of them.

You just can't do this. If your site can be displayed in a browser, screenshots can be taken of it (also copies of it can be stored locally and manipulated, the content can be scraped via non-browser technologies, etc., etc.).

  • Reminds me on those old useless 'do not copy my source-code' alerts on right clicks. Hilarious :) – Lain Dec 08 '16 at 08:51
