What good is an HP plotter?

In the days when I used a vector network analyser (1989-92) plotters were already a thing of the past. We had laser printers then which would print the chart in a few seconds and for the important stuff (presentations!) a color-sublimation printer which was able to print beautiful A3 sized images on paper or transparency within a few minutes. Very expensive and an incredible waste of plastic foil.

But you are right, for pure line charts the HP felt tip pens last very long. But only if you take them out of the plotter after use and put the caps back on - the spring loaded caps inside the plotter don't seal them properly!
