Use the mouse button to select the file you wish to download.  If you are using a compatible web browser you can choose to "open the file" (recommended) or "save to disk".  If you open the file in the web browser, you can print directly from the web browser.  If you save the file to disk, you can open and print it later.  Incompatible web browsers will allow you to only save to disk, in which case you will need  to open the files using Acrobat Reader (freeware) later. If you need a copy of Acrobat Reader to open these files you may download Acrobat Reader 7.0 and install it on your computer: (If you do not have the Adobe Acrobat Reader 7.0, you may download it as provided by Adobe^TM www.adobe.com).  Once saved on your computer, install the program.
