	Another approach is to export a .svg file with Processing and to convert it to .hpgl with InkScape. (The files produced by inkscape are not really compatible with my “HP7475A_feed_hpgl_file_01” sketch yet). InkScape also has the option to directly send graphics to the plotter, but I had no good experience with that. It also needs original HP Pens (or 3d printed adaptors), as it sends SP; commands, which let the plotter attempt to change the pen, before beginning to draw.
