I know this is a bad code, and it is not the best solution, but this works for web applications at least.
It gets the canvas element and make a download link with this.

         function downloadQR() {
		var canvas = document.getElementsByTagName("canvas")[0];
		var img = canvas.toDataURL("image/png");
		var a = document.createElement('a');
		
		a.href = img;
		a.download = "image_qr.png";
		document.body.appendChild(a);
		a.click();
		document.body.removeChild(a);
	}
