mailing labels from a spread

I have been looking in this help database, trying to find the instructions from the online books, all to NO success.
I want to make a form that looks like the attached, C:\fakepath\Address Book (trying to setup) 2020.odt, and prints the data from my addressbook spreadsheet. Double-sided printing and each is individual. I was almost there, but the program insisted on only giving me letters or emails and that’s not what I want. Years ago I was able to do this in the simple program Microsoft Works. But the more complex programs don’t seem to be able to do this. Please help. I should be able to do this with “labels”, but haven’t had success yet.


Sounds like ordinary label processing except for:

Double-sided printing and each is individual.

How is a label double sided? And what is each is individual?
