In March 2018, I was specifically searching for a way to print family group sheets and came across this Q&A.
I am glad I did because the answer from Harry was exactly what I was looking for.
Anyone coming across this now, the link above still works, but redirects to one a little simpler.
It's now
www.ancestry.com/family-tree/tree/TREE_ID/family/familygroup
As stated above, replace TREE_ID with the first set of numbers found in the web address on the person's profile page.
