The other day I had to help a friend online, I needed to publish a paper in PDF.
I found that there is little clear information how.
Here are two plugins to publish in their XPS and PDF and Word files or Excel.
2007 Microsoft Office Add-in: Microsoft Save as PDF or XPS,
2007 Microsoft Office Add-in: Microsoft Save as PDF,
allows you to export and save to the PDF format in eight 2007 Microsoft Office programs. It also allows you to send files as e-mail attachments in the PDF format in a subset of these programs.
