Check for when a user has selected to print using javascript

Question

When a user chooses \"File > Print\" on a browser such as Firefox or Internet Explorer, or clicks on a link that runs the below javascript

window.print();
         


        

Answer 1

You can do:

window.old_print=window.print
window.print=function() {
    alert('doing things');
    window.old_print();
}

but this will only catch calls to print() from inside the page javascript.

Did you try putting !important on print-specific stylesheet?
