有一个名为onPrintDialogClose的选项，它在“打印”对话框关闭后触发。

printJS({
    type: "html",  // Include other option if needed like style , css .....
    onPrintDialogClose: closedWindow 
  });
}

function closedWindow() {
  alert("Window is closed "); // What ever you want to do after window is closed .
}

我在下面的链接https://github.com/crabbly/Print.js/issues/348中尝试了slebetman的解决方案，它对我很好

let focuser = setInterval(() => window.dispatchEvent(new Event('focus')), 500);

printJs({

    printable: url,

   onPrintDialogClose: () => {

   clearInterval(focuser);

   // do your thing..

},

onError: () => {

   clearInterval(focuser);

    // do your thing..

  }

});
