When printing a WEB-page with custom CSS the output is not as good as in the browser

I am using custom CSS to format a Wikipedia Webpage and trying to convert it into PDF. Irrespective of the add-on, e.g. User JavaScript and CSS or Stylish , the result in the browser looks very nice and neat, but when I call the Print Dialog Box, the styling of fonts and paragraphs is no longer that coherent. My aim is to attain a good layout for printing into a PDF file. The CSS code is below, although however, I fiddle with it, it always produces different results in the Browser and in the Print Dialog Box, and, hence, in the PDF. @media all { body { padding: 0 0%; font-family: jaf-bernino-s
