Edit a Word Document in Print Preview
While viewing a Word document in the Print Preview window, you might notice a typo, or something else that you’d like to fix quickly, before printing. However, the pointer is a magnifying glass, and when you click on the page you just zoom in or out.
To edit the document, you can turn off the magnifier:
In Excel 2003, click the Magnifier button on the toolbar, to turn it off.
After you turn off the Magnifier, the pointer will change to an I-beam, and you can click on the document and edit it.
