I use this utility all the time to convert Microsoft Word and Publisher documents to pdf.

It supports multiple file formats, is very easy to use, and it is FREE.

Just upload the document you want to convert, enter your email address, and in a few minutes you will receive an email with the converted document.

Very handy free tool.
