You can determine which one by typing ...

        __gnuplot_version__

Another possibility is that the error is related so a specific plot object. Do 
you get the error for ...

        clf
        plolt (0:10)
        print -demf "-S640,480" test.emf

If not, can you provide a simple example which does?

I don't presently have version 4.4 or 4.5 installed, but have been meaning to 
do so. I'll take a look to see if that is straight forward.
