Plotter Calibration?

We often use full size (1:1) large format (42 inch wide roll feed) plotted drawings to use as 'build' guides on our custom ornamental products. is it possible to calibrate the plotter output to maximize the accuracy of the plotted drawing? AutoCAD has a calibration utility built into its printer interface (separate from the specific plotter driver), but I have not found a similar functionality in the DrafSight interface. To this point the plots I have made have been close, but not accurate. I need this capability. Does it exist?
