The easiest way probably is to photocopy the document
Or if you need to amend the text get some one with a scanner and optical character recognition software to convert your existing paper copy back to a Word document or RTF.
If you had Word configured to produce a timed backup it is possible there are traces of earler versions of the document.
Look at Word configuration to find out where temporary files would be stored
(probably Word Options / Advanced File Locations (looking at my Word 2007))
BUT the more you use this computer and the fuller the hard disk is the less chance of recovering the file
You have learnt a hard lesson about the importance of giving the Office document a name and saving regularly
