I was asked the other day by a staff member how he could open an Apple iWorks file for printing on his Windows 7 PC.
This process to do this is quite simple. The steps are as follows:

1. Change the file extension of the Pages file from .pages to .zip
   (You must first show file extensions in windows explorer)
   
   
2. Open the newly renamed zip file and browse to the QuickLook folder.
3. The QuickLook folder will contain a PDF file named Preview.pdf. This file is a PDF version of the original Apple iWork Pages document.

Done!
