how to detect browser print (ctrl+p) using jquery

Question

I have a button on my page called "Print". clicking on which will trigger a jQuery function.

I need to call the same jQuery function when user hits Alt+f+p or ctrl+p

How do I do that?

I tried to do that with matchMedia but no luck

 if (window.matchMedia('print').matches) {
        alert("print using browser");
    }

There is not a standard way to do that as far as I know.

IE and FF offer own function calls,

In IE there are the nonstandard window.onBeforePrint() and window.onAfterPrint() event listeners. There isn't a non-IE way to do it that I know of, however.

Firefox 6 now supports beforeprint and afterprint https://developer.mozilla.org/en/Printing#Detecting_print_requests

A universally working solution might be to just listen for CMD+P.
