Select the receipt width that matches your printer (58mm or 80mm). To add a logo or image, click + Upload. Check the preview to verify the output. When finished, click Save.

Note : It is recommended to use black-and-white logo images for optimal clarity on thermal receipt printers. Very light or very dark images may be converted to darker grayscale when printed.
