We have 3 versions of Autocad 2002 on XP pro, P4, 512 Ram Sending a plot to HP 750c plotter file size for 1 No. computer is up to 3 times larger. This is the same for all drawings sent to the plotter. Plotter driver versions are the same - HP V4.63 The same plot style is also used. What would cause this to occur? Many thanks Hans
