Cannot print via USB connection to AirPort Express
I have been using my printer via a USB connection to my AirPort Express. Recently, I purchased a TimeCapsule, and restructured my network so that the TimeCapsule was the source of the network, and the Express was merely extending it. My printer is still connected to the Express, but I am no longer able to locate it on the network, and my computer will not print to it.
What am I missing?
MacBook, OS X Mountain Lion (10.8.2)
