We recently upgraded to AutoCAD 2014 from 2010 and noticed that the DWGtoPDF.pc3 was printing some fonts really pointy, similar to "Bat Wings".
Below is the solution I found in case anyone out there is in need:
Download DWG TrueView 2014.
Replace the Drv folder from the AutoCAD installation folder w/ the one from TrueView:
Copy
C:\Program Files\Autodesk\DWG TrueView 2014\Drv
To
C:\Program Files\Autodesk\AutoCAD 2014\Drv
Now my pdfs are printing correctly
HTH,
