Office of Information Technology has reported vulnerabilities or issues with Brother, Dell and other low cost printers, mostly due to those printers were designed for Home use or the printer was designed to be replaced within a 2 year period of time. If the home use printer in question does not come with a firewall or other method of restricting access it can be used to launch man-in-the-middle or denial-of-service attacks and cannot be connected to any campus network.
