To print the contents of an iframe in TypeScript, you can use the contentWindow property of the iframe element to access the document within the iframe and then call the print() method on it.


Here is a basic example of how you can achieve this:

1
2
3
4
5
6
7
const iframe = document.getElementById("myIframe") as HTMLIFrameElement;
const iframeDoc = iframe.contentWindow?.document;

if (iframeDoc) {
  iframeDoc.body.focus();
  iframeDoc.execCommand("print", false, null);
}


In this code snippet, replace "myIframe" with the ID of your iframe element. The contentWindow property of the iframe element gives you access to the document inside the iframe. We then call the print() method on the iframe document to trigger the print dialog.


Remember to handle any errors or edge cases that may occur, such as the iframe not being loaded or the print method not being supported by the browser.
