NEED HELP :(
Eric and Kipp have the right of it. Fix the printer driver or switch to a driver that works like Microsoft Print to PDF as your default printer.
Just a note that both of the things you are doing create Section breaks in Word or change the settings for the whole document. If you are changing Margins for part of your document, change Indents instead. Doing this dramatically reduces the complexity of the file. Change the Indents using a paragraph style, rather than by directly changing them in each paragraph.
P.S. In the future when posting in a help forum, don't use "Need Help" or "Microsoft Word Problem" for the title. Give something about the nature of the problem in the title. It will get you faster responses. For instance, here, an appropriate title might be: Word locks up when I try to change margins or orientation.
The people answering questions here are volunteers, your fellow users. None of us are all-knowing, so we look for questions where we might be able to help. Everyone posting here needs help. This is not a criticism!
