Exactly. I only found you because you listed the BUILD #. I have same problem. If you select Print Gridlines, and save the file, it changes to Print Headings. If you select Print Headings and save the file, it changes to Print Gridlines. All my files are set to view both (Headings & Gridlines), but only print gridlines, not headings. Starting a few days ago, it opens with Print Headings box checked and Print Gridlines unchecked. 3 PC's. Two are Windows 7 Pro, 1 is Windows 10. I have another laptop with Build 16.0.8067.2115 and it works fine.

I started having the same issue yesterday.  It is occurring on all of my saved files.  I changed it to print the gridlines, unchecked print row headings, saved them, and it changed it all back again on all of my files I opened today.  I haven't tried any other computers but I use Excel all day long and it is time consuming to have to change that on every file I print.  I use MS Office 2016.
