The new version of the DWFwriter driver for Windows is much more optimized than the release 1.
DWFwriter Alpha: Click Here
On install you nwill get a message about the driver not being signed by Microsoft, ignore that message as the driver under development is not signed yet and you can ignore and continue the installation. After installation the DWFwriter will show in your Windows System printers.
Please note this is early alpha and is unsupported so use at your own risk.
Update: DWF Writer 2 is available now from: http://www.autodesk.com/dwfwriter
