I don't know if there are other softwares as Bhaver suggested to convert DBF to PDF, but I use the freeware software called PDFcreator (
http://www.pdfforge.org/products/pdfcreator ) it's a nice software to converto every document to PDF format.
In your case, you will have the PDF file opening the DBF file in MS Access and printing the document to PDF virtual printer.
Hope that it helps.

Paolo
