This freeware has worked pretty good in my small tests and does not require GhostScript, works on Vista and also 64-bit systems.
If you plot from AutoCAD and use TrueType fonts they will be converted to text if you make that change in in the plotter properties.
You need to change the Properties of the plotter (Plotter Configuration
Editor)>Device and Document Settings>Graphics>TrueType Text to "as text". Save this to a PC3 that you use.
Another thing that is great is that it's free even to print to PDF for commercial usage.
Test of the PDF converter was done using AutoCAD 2009.
