Based on Julian's responses to my questions about formatting html to correctly show font size and page breaks, it sounds like I should consider using wpPDF to produce a pdf and send that to the web page. Would that produce a more faithful copy of my wptools document?
Also, I've resisted upgrading to wpTools 5 because of existing documents that might need conversion. Scouring the forums here, I find one message that says there's no problem with formatting, but otherwise very little information on what needs to be done to upgrade documents. Is the internal document format the same in v5 as it was in v4? My memory from a couple of years ago is that there were basic differences.
