title: How to disable printscreen with javascript?
body: <p>I want to make function in javascript which change value of clipboard after the printscreen was used. Is that possible? </p>
  
  <p><code>$(document).keyup(function(e){
    if(e.keyCode == 44) 
      //change clipboard value code
  });</code></p>
  
  <p>EDIT: I found ZeroClipboard library but every tutorial is about copy with button. I want just change the value of clipboard. </p>
