Clarification: no solutions are offered by Microsoft here. This is not a Microsoft forum and the posters are volunteers, your fellow users, usually with a lot of training and experience on Word.
The Microsoft article you link is about screen display, yes. It is not about pdf. If there is a fixed line size and it is less than that required for ascenders and decenders of the font, those will not be displayed or printed. That is a reality of the way fonts are constructed, I believe.
This thread is about pdf results. Yes, it is often better to start a new thread, but your question is still on-topic for this one.
Are you aware of any word processing program that does not produce the same results with the same fonts and spacing?
I am not, but that is not surprising nor especially meaningful.
I have two direct questions for you:
- What happens if, viewing the pdf, you change the screen zoom?
- What is the result when you print the pdf?
