From any of the Googlegear machines in the lab, from any application, such as Word, Powerpoint, or any other text editor or program, you can create an Adobe PDF file:

If you want to create a PDF of the document you are currently working on, from any application, choose File > Print.

Select Adobe Distiller as your printer and print your document.

A window will pop up, asking you where you would like to save your document as a PDF. Select your U:\ drive, or any other convenient location to save the document. Distiller will grind away for a moment and, voila!, the file it saves will be a PDF version of the document on which you are working.
