Description Woody Lee 2022-09-14 01:41:29 PDT

The afterprint event should be fired after print dialog closed.
Ensure action executes after print, shuch as change some content or close window etc.

It only reproduces in iOS/iPadOS Safari, version 15.6 and 16.

Another question: window can't close while the print dialog shown, is it a standard interaction?

Can you attach a test case to reproduce this issue? Thanks!

A simple example:

var win = window.open('');
win.document.write('<div>Test</div>');
win.addEventListener('afterprint', (e) => console.log(e) );
win.print();

The event log will fired before print dialog closed.
