is this the correct way to print image? because the image is not printed as a pictureā€¦ did i miss something here?

printMyImage() {

		var image = new Image();
    image.crossOrigin='Anonymous';
		image.src = 'assets/imgs/d.jpeg';
		image.onload = function() {

    var canvas = document.createElement('canvas');
    console.log(canvas);
    canvas.width=image.width;
    canvas.height=image.height;
		var context = canvas.getContext('2d');
		context.drawImage(image,0, 0);
		var imageData = canvas.toDataURL('assets/imgs/d.jpeg').replace(/^data:image\/(png|jpg|jpeg);base64,/, ""); //remove mimetype
    console.log(imageData);
		window.DatecsPrinter.printImage(
			imageData, //base64
			canvas.width,
			canvas.height,
			1,
		function(success) {
			alert(JSON.stringify(success));
			// this.printQRcode();
			// this.provideFeed();
			},
		function(error) {
			  alert(JSON.stringify(error));
			}
		)};
}
