Writer. on Save to pdf 4.3 changes the pagination and 4.4.5 changes the justification

When I save my document to pdf Writer 4.3 changes the pagination of the document and Writer 4.4.5 left-aligns my justified text. How can get an accurate pdf file suitable for publication?

I think I have answered my own question. By opening the Print dialogue page, and then selecting the PDF button in the bottom left, and then choosing Save to PDF, I have been able to get accurate PDFs.
