How to Save an Office 2013 File as a PDF
Click the Create a PDF/XPS button.
The Publish as PDF or XPS dialog box appears. If your goal is to create an XPS file, not a PDF file, open the Save As Type drop-down list and choose XPS Document (*.xps). Microsoft created the XPS format to compete with the PDF format.
As are PDF files, XPS files are meant to present data from different programs, in this case in Internet Explorer. However, the XPS format is not nearly as well known or frequently used as the PDF format.
