Sadly, window.print() doesn't return any value. So, there's no way to know if the user clicked Save or Cancel. It's more of your operating system's job to watch what's going on in there. There're, however, two event handlers: window.onbeforeprint and window.onafterprint.

The afterprint event is raised after the user prints or aborts a print dialog.

But again, it's a simple event and it's not telling you which option is selected by the user. And also these two events are not well supported.
