I have tried to save results but can't. Tried to print but it only covers a couple of pages. What am I missing?
It sounds from your question that your main objective is to print many generations from FamilySearch. FamilySearch only has limited printing functionality (several generations). The attached Knowledge articles show you options for printing on FamilySearch.
Some of the FamilySearch partners have other options for printing information from Family Tree. These programs offer a wider variety of printing options than you find on the FamilySearch website.
Downloading your tree from FamilySearch requires you to use third-party software that is certified by FamilySearch to work with its tree, you can find partner software from the Solutions Gallery at the bottom of FamilySearch's homepage.
Here's a link on how to download your Family Tree from FamilySearch :
hope this helps, all the best
