Please be advised that wireless printers may not work on the Harvard wireless network. These devices are currently unsupported by Harvard University Information Technology.
Wireless printers are designed for, and work well in, simple home networks. They require multicast services, which are unavailable on most campus networks. Many universities are experiencing the same issue with wireless printing. Wireless printing may work in some locations from VPN.
Note that, on a computer with a wired and a wireless connection (such as most laptops and notebooks), there will be one MAC Address for the wired (Ethernet) connection and another for the wireless connection.
