Pens should be the least of worries. They are still sold new by HP and there always have been plenty of third party suppliers. When I still used my 9872C flatbed plotter I mainly used third party ballpoint pens which take standard fountain pen refills. That cut the cost of plotting down to 1/10 compared to using the original HP felt tip pens. I even have a full set of compatible Rotring "Rapidograph" drawing pens for China ink used for technical drawings. They produced excellent plots but had the usual problem of these pens of drying out quickly when not in use followed by y tedious job of getting them working again.
