Client asked me to set up his family’s HP Envy 120 All-In-One as a wireless printer to work with their Macs and iPhones. Initially, the printer wouldn’t recognize the wireless network (an AirPort Extreme) until I made a simple configuration change.
I originally set up my client’s AirPort router as a closed (hidden) system so the wireless network couldn’t be seen by neighbors. After failing several times to try to get the Envy’s control panel to accept the SSID and password, I decided to deactivate the closed setting in the AirPort configuration screen that so that the wireless network could be seen publicly. Doing so allowed the printer to see and connect to the wireless network for the first time. After successfully running off a few test prints, I went back into the AirPort Utility to close the network. I checked the printer again, and it still maintained its connection to the wireless network.
