Solution? Simple: Under your printers in Windows, right-click Adobe PDF, choose Properties > General tab > Printing Preferences. Make sure the checkbox for "Rely on system fonts; do not use document fonts" is off.
Also, the same thing can happen on the online Acrobat.com tool:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
Unless the document you upload has the fonts it needs embedded within it, it will throw an exception. The conversion server has only so many fonts; there's no way it can have every possible typeface that people might use.
