This should work (tested in Chrome, Safari and Firefox) (jsfiddle): 

$(window).keydown(function(evt){ 
    if((evt.which == "80" && ( evt.metaKey || evt.ctrlKey ))){  
            evt.preventDefault(); 
            alert('not printing anything here');
    }  
});​

edit: a no jQuery version:

document.addEventListener('keydown',function(evt){
    if((evt.which == "80" && ( evt.metaKey || evt.ctrlKey ))){  
            evt.preventDefault(); 
            alert('not printing anything here');
    }  
});
