In the image below I printed DWF files from a non Autodesk CAD application as well as even the almost 10 year old AutoCAD R12 for Windows. I have printed from many non Autodesk applications. The DWF format is a very nice and much smaller file than an Adobe PDF which is appropriate for your Word documents, not your design data. There is a free viewer that is a small download and loads very fast. All you need to do is enroll for the DWFwriter 2 beta at:
http://betaprograms.autodesk.com/betaweb.htm
or wait for the final release. It is a very nice tool and installs as a standard Windows system printer driver so you can virtually print a DWF from any Windows based application.
