E-mail "order create" length

Hi,
since 20.08.2019, when I receive the automatic email of a created order, it arrives on two pages, even if the order is short. The second page is empty and with a gray background. I attach screenshots of the print preview:

The order ends in the middle of the first page, but there are 2 pages to print, the second empty. Until 19.08.2019 instead, the page to be printed ended with the order total. Is it possible to fix this situation and print only the order automatically without telling the printing program to print only the pages containing the order and not the empty ones?

Thanks in advance

Hi Nicolas,
it's just the standard print preview of my Mac.

Your words made me reflect on why this happens on our computers, all Apple, all with only the default client (Mail), and all with the box load / not load images in the mail, disabled. If I check images loading, everything is perfect, but if I don't want the images loaded and I want a text-only version for notifications to us, then the email gets longer than a blank page with grey background.. I'll fix it but thanks, I've found that it could be a problem with our mail client. Thank you.
