I have two Ultimaker 3 printers in use in a lab at my university. Recently, students who have not had training to use the printers have been trying to print for their projects, causing serious damage on several occasions. We cannot restrict physical access to the room and I cannot supervise the printers all day, every day. If we block off the USB ports, Is there any way of controlling who has access to the printers via the network?
If not, how do other people control access to their printers in these sort of environments?
