Disabling the print screen option in flash

You want to disable the print screen option in your flash file(actionscript 2.0), so that the user will not be able to take the screen shot of the information presented?

Here is the code:

// Use System.setClipboard function, and set the clipboard to something you want.

this.onEnterFrame = function (){
if (Key.isDown(44)) {
System.setClipboard("YOU CAN NOT COPY- PASTE ME!");
}
}
