How do I convert PDF to PDF/A? - No preference of operating system to run the script or program.
(this is for printing directly on my printer; however the printer requires print formats with fonts included)
you can try a web service like this one (2mb limit though), and almost all commercial editors allow you to save in PDF/A in either the Save As ... feature or the document properties.

I was able to get what I was looking for using an open-source PDF printer by the name "PDFCreator".
Embedding all fonts in a PDF is not the same thing as having a file that complies with the PDF/A (ISO 19005) set of standards. Compliance with PDF/A requires many more features of PDF to be enabled (or disabled) accordingly.
