window.print() renders QR code svg as black square in print preview. firefox only #338

My angular application uses window.print() on a page which contains a QR code generated with this library. On firefox, the print preview transposes a black square over the QR code, which is in svg format. It appears the black square can be removed by using the dev console to remove the "fill" attribute from the first element which is a child of the element which is the QR code (this is why I say the black square an overlay, not replacing the QR code).

Not sure if this is a known issue using this package in firefox, but if so, is there maybe a configuration step that was missed? Thanks

You need to check this option of "print background" in the firefox print setting.
