print multiple copies in php using window.print

I am trying to print multiple copies of just a product name on a sticker. No of copies would be passed by popup onto print.php page.
I tried using while loop to use window.print but it prints only 1 copy.
heres my code:

function PrintPage() {
     var count = <?echo $prnt?>;
while (count >0){
       // alert("print");
    window.print();
    count--;
    
}
 window.close();

}
document.loaded = function(){
    
}
window.addEventListener('DOMContentLoaded', (event) => {
    PrintPage()
    setTimeout(function(){ window.close() },750)
});

used alert to debug if loops works, its showing.
I know this is regularly asked question ,however, I tried and its not working for me. Please help
