Can you help with technical and legal background information on how to use
a True-Type copyrighted font correctly with laypeople and printers?

Legally you can't unless the font publisher allows it.

Have you searched the web for a similar copyright-free font so you can avoid all this nonsense? You could have everyone design with the free font and then you could substitute your legally
purchased version when the document is finished and sent to the publisher.

The commercial printer may need to purchase the font as well.
