If it's just really the AGP graph and other stuff you get on the Statistics page, you can select the 7, 30 or 90 day options, then there's a share icon to the right of those buttons which lets you email and the other sort of things which a share icon does.
In practice, all it's really doing is taking a screenshot of the page, so it's probably easiet just, erm, taking a screenshot and printing it off like any other screenshot
I've never needed or wanted to share stats to any real degree, tend just to wave the phone a bit at docs, so I haven't looked into the more elaborate reports which are apparently available through Nightscout - you'd have to set up an account for that.
