thanks for the reply, just seems strange that the drawing was made in autocad 2010 and plotted fine on my old computer but then i moved to a new one, installed cad 2012 this time, redownloaded DoPDF and prints massive text.

When i use doPDF some of the text is extremely large in comparison to what it is on the screen, how can i stop this?
This is in AutoCAD 2012
