Happy day,

Silly question first....is the PDF software on the server and workstations? 

Less silly question section...did you go to the server, log in to PS and File>print options> printer/dms/pdf setup, choose the software you use (foxit, adobe, etc)? 

I have not yet found out why some settings that I make on the server do not populate to the workstations...which forms to print, order, etc...but those two questions were my ideas of things to check.
