EzeScan does not include a TIFF printer driver out of the box.
However there is a PDF/TIFF printer driver at http://www.pdfforge.org/products/pdfcreator. It is easy to use and free (GPL) software.
So if you want to create TIFF files from Email, Word, Powerpoint, or any windows application that can File → Print then we could suggest you take a look at the PDF Creator product. The website includes an MSI package that makes installation.
