Right-click on the file and select 'Properties'. The 'General' tab will probably be preselected; if not, click on it. If there's a tick against 'Read only' click to remove it and then click on 'Apply' followed by 'OK'. (If there's no tick, simply click 'OK').
Almost any word-processor should be able to open the file, allowing you to edit it and print from it. However you've not told us which word processor (if any) you've got on your computer. If you've not got anything suitable already, download and install OpenOffice:

(Click 'Download full installation'. Save the file to your hard drive. Double-click on it and follow the instructions).
Once you've ensured that the file isn't 'read only' and that you've got compatible software on your computer you should then be able to open, edit and print the file.
