We have a surplus HP T790 plotter available – free to anyone who can come and pick it up. It is only a couple of years old and still works fine except that it need new printheads. The base has been disconnected so the two
piece could probably fit into a larger vehicle. See the link below for plotter details. Let me know if you’re interested.
