I managed to get a good font size and margins, but can't seem to fix the issue of page breaks between headers. I tried heuristic processing and "insert blank line between paragraphs" and a couple other things, no dice.
Just to be clear, I provided 2 examples (click the image to make it larger).
Oh, another quick question. I noticed when bulk converting that the spacing between paragraphs wasn't consistent between pdfs. Is there a way to standardize it to some arbitrary value? Eg/ 0.5 inches.
