EWF6 Plotting issues

We have two computers at work both of them are running Auto 2010 but my computer is the LT version and the other guy's is the full version. When plotting to dwg files the other guy uses the DWF6 ePlot DETE pc3 plotter and I don't have that plotter. The one I have is the DWF6 ePlot.pc3 plotter. When he plots our maps they look great but when I plot them they are horrible. When I zoom in they are huge thick lines and you can't tell whats what. We are opening the same map and all the layer properties are the same the only difference that I can tell is he has the DETE plotter. My question is can I download that DETE plotter to my LT version? If so how and do you think this will make any difference? Thanks

One other thing I should mention is I was able to plot our maps using the DWF6 ePlot.Pc3 using our old base map but we recently received a updated base map from our city's IT department and when I try to plot these new maps they don't work I get the thick lines and you can't read anything but when the other guy plots it we seem to be able to read it just fine.
