Word and PowerPoint documents suddenly shows unformatted text and boxes

Problem: When you open a Word or PowerPoint document which had been correctly saved days ago, some text or text boxes looks unformatted or are not displaying as you remember when the document was saved.

Troubleshooting: Check your default printer, may be it was changed to an local offline or generic printer or, if it is a network printer, it was disconnected a lot of days from the print server. Word and PowerPoint are particular reliant on Printer settings in order to show document content.
