It's very easy, all you need to do to save the documents in Word 2007 in the
Word 2003 format.  You can either do this individually or set the default for
this.  He said the default click on the office icon and then options (bottom
right of the window) and go to the section for save, the top pull down will
allow you to select the format to save documents in.

Hope this helps,

If you have a home network so that the two computers can communicate, you
can enable Windows File and Print Sharing on the Word 2003 computer and
share the printer. Then run the Add Printer wizard on the Word 2007 computer
and add the printer as a networked printer. With that setup you can select
the printer on the other computer as the default printer on the Word 2007
computer, and just print normally.

Or maybe you should move the printer from one computer to the other.

Otherwise, you have two choices:

- In Word 2007, save the document in Word 97-2003 format. That's on the
"Save as type" dropdown in the Save As dialog, or you click the Office
button, hover over the Save As item, and choose Word 97-2003 Document from
the menu. The document will open in Word 2003, but some of the new features
(such as SmartArt) won't be  completely preserved. When you save in the
older format, Word 2007 will tell you about any changes it has to make.

- Download and install the Office 2007 Compatbility Pack on the computer
that has Word 2003. It's at
http://www.microsoft.com/downloads/details.aspx?FamilyId=941B3470-3AE9-4AEE-8F43
-C6BB74CD1466.
This will let Word 2003 open documents that are saved in Word 2007 format.
Again, some of the new features won't be preserved if you edit the document
and then take it back to Word 2007. Just printing it shouldn't have any
problems.
