Plotting to PDF in AutoCAD 2014 works just fine and PDFs can be viewed in all of their glory. The issue comes about when printing these documents. When our engineer prints, all of the uppercase letter Bs are missing from the printed files title blocks only. Printer is a Kyocera FS-8000i with current drivers.
