Overview: Connect your computer directly (wirelessly) to the printer to set it up on the network, then, back on the network, set up the printer on your computer.
- Have at hand your network's SSID (network name), authentication type (eg, WPA2/AES), and password (or "key"). You won't have access to the network (to look things up (or to watch the above video), unless you can use another computer) during the following process (because you will be connected to the printer's wi-fi instead).
- At the printer, restore its network defaults. Make sure its wireless transmitter is on.
- At the printer, print out its network configuration page. Note the network name (SSID; probably "hpsetup") and the URL (http://…) for the printer's embedded web server.
- Connect your computer's wi-fi to the device network of the printer.
- Open a browser page to the URL of the printer's web server.
- In the browser, go to the Networking tab, and in the Wireless frame go to the Advanced tab. Enter your network's (not the printer's) SSID (remember: case-sensitive), activate the Infrastructure area, and activate and enter the authentication information. Apply. The printer will now be switched to the network, so the URL won't reload when that's done.
- After a bit, print out the printer's network configuration page again. It should confirm that it is now connected to your network.
- Connect your computer's wi-fi to your network.
- The printer should now be available in the System Preferences Print pane.
