Your files are so large because you've saved them with embedded fonts. In the docx file, that's about 5½ Mb of embedded fonts. Without those, the docx file becomes just 47Kb and the doc file becomes just 52Kb.

Regardless, I'm not seeing the problem depicted in your first post in either file.

Given that Word uses the active printer driver to manage document layout, the symptoms suggest you have a faulty printer driver. Try changing to a different one (e.g. the Windows PDF 'printer'). If the problem resolves itself when you do that, it's definitely a printer driver problem. Either way, you should ensure you're using the printer maker's latest drivers for your printer. Even reinstalling the current driver might suffice if it's the latest version.
