Q. How should I set up a wireless printer in a residence hall?

The best way to get the printer on wireless is using BYOD - the IT website has instructions.  That having been said, that will put them in the BYOD network, and auto discovery probably won't work for the desktop/laptop.

In order to print to the printer on the BYOD network, they'll either need to be plugged into the access point (it puts the wired connections in the same VLAN), or connected to BYOD rather than the normal campus network.  It's probably possible to map the printer IP directly if you're on the normal wireless, but that printer IP can and will change if it's off for more than a couple of hours due to DHCP.
