javascript - Executing function before page gets to window.print()

I have a page that calls window.print(); at the bottom of the page. I have no way of accessing the code around window.print(); Its generated by the server and I can't touch it. Basically because of IE I need to execute a bit of javascript before the print dialog comes up but after the page has loaded. I can't do this because as soon as it gets to window.print(); the print dialog comes up. I still need to print but first I need to run myFunction() then I can window.print();

<html><head></head><body></body><!--no access from here--><script>window.print();</script></html>

You should be able to override it like so...

var _print = window.print;
window.print = function() {
  alert("Hi!");
  // do stuff
  _print();
}
