SaveAs .pdf appears to truncate last page ... Anything I'm missing?
It appears that it won't print page 4, and beyond, no matter what - many experiments, but prints first three pages correctly.
This one works fine, so it's has got to be something to do with my Notebook that is causing it to stop generating the .pdf after three pages.
Resolved with help from Mathematica Support. (Embarrassing but necessary.)
It seems that the Mathematica Print command was set to print Pages 1-3 (unbeknownst to me) - and this becomes a property of the Notebook, until changed.
Thus SaveAs to .pdf creates only a 3-page .pdf.
Changing Mathematica Print command back to Print All FOR THAT NOTEBOOK enables SaveAs to .pdf to create .pdf of entire document.
This was confusing because a test Notebook to .pdf worked fine, because, obviously, it had defaulted to Print All.
