Short of an extension (if one exists) I don't think you can do this in Qlik Sense.
You could do it in Nprinting. Of course you would have to purchase this if you don't already have it. I don't think that there is a way to trigger the nPrinting task based on a QS task. So you would be guessing at the correct time to run the nPrinting task.
It could pull in the latest image of the chart and then email it or put it out on the Newstand from someone to look at it.
