Rule number one : don’t screw around with the browser of your enduser. Say that you were able to filter out the print menu item. What about the keyboard combination ctrl + P? You could override that again with some javascript but that only leaves the enduser clueless as you’re overriding standard functionality and that’s a big nono.

Besides that, you’re using javascript. That can be turned off by an enduser and then your clipboard erasing script also doesn’t work anymore. Poof and there goes your protection level.

try it . .

Thank you
