I'd agree if the ink used is "india ink" (carbon black based ink --
the classic stuff used in Chinese/Japanese calligraphy). At one
point, pen plotters could accept drafting pens, such as the famous
Rotring/Rapidograph. Fill one with india ink and plot on vellum, keep
FWIW, the thread on the pen carriage of the Tektronix 4662 plotter (and I
assume the 4661, which seems to be mechanically very similar) is
identical to that on Rotring pens. Handy....
You can get metal-tip drafting pens for HP plotters too, but I have no
idea what sort of ink they contain. Most of them come pre-filled...
