How to do print() instead of showing

[Helkyd]

Hi,
Can you please explain me how to do PRINT() instead of showing the PDF ?
For example in this code
if (order_manage.print_modal) {
order_manage.print_modal.set_props(props);
order_manage.print_modal.set_title(title);
order_manage.print_modal.reload().show();

I would llike to instead of show() to print()

Thanks
