[Theme: Twenty Fourteen] How move main title in @media print

Such is my confusion that I don’t even know what element to change!
If you try to print
http://www.dynamiquecorporelle.fr/wp/frais-inscriptions-contact/bulletin-dinscription-2
you will a horrible gap above Bulletin d’Inscription.
I’ve tried hasty swallowing of css guides but I cannot work out what html, class or div to change in my child theme style.css file!
Help much appreciated.
