If only we had a decent way to print those html pages to pdf. But It seems like the print-css is kind of neglected. The stuff barely is doing what it should(page-break and friends).

Neither can you really use min-height=20mm. A pity. And the nicer pdf creators (weasyprint) don't understand the new css rules like flexbox or grid.

So we are still stuck. No easy way to force a footer to the end of a printed page via css.
