We bought several old pen plotters as gov't surplus. Finding drivers for them was impossible from the mfgs. There is a software co that writes plotter drivers, but their software was more expensive than a new plotter. At that time, one of my 2d programs was turbocad. It was crap software to use, but had great post processing for all of the plotters we bought.
We since narrowed our plotter selection down to a single plotter ( draftmaster rx plus ) which kinda sorta works within SW. When I need a good plot, I still export the drawing as a .dxf and plot from turbocad. You might check to see if it still has similar post processing capabilities for plotters ( think you can d/l a fully funtional trial ). For free... hard to go wrong with any plotter.
