Is there a way to detect which port on an ethernet switch a device is connected to?

ethernet

Since the wall jack is typically always connected to the same port on the switch I would like to be able to know which device is connected at a specific location. In my case I am talking about printers. I have code to go out on the network and find the IP Address of all of my printers, but would like to be able to update a server based on a printer being swapped out of a location for maintenance or repair. Is there a method for determining a port connection?
