does anyone know if Riso Kagaku makes all of its own components and consumables? riso kagaku is not on the BDS list but im wondering if there are any tricky supply chain things where Riso might get components made by HP or something. trying to figure out if Riso can accurately be described as printing without giving any money to HP or any other more evil corporation. relatedly, how much of their inks are actually oil as opposed to petroleum-derived substances? everyone says the inks are more eco-friendly but what does that really mean? thanks!
