Those cartridges are still well in use in the industrial field. They are incredibly robust. I have seen them on automated wood cutting plants to put serial numbers on freshly cut wood. They are also used in professional large-format plotters for architects. There is an official CIS available, but I forgot where I found it.
I have known about these for a while, but they are quite large and require hundreds of connectors for the five colors that I want for full-color 3D printing.
