An error occurred while trying to add the selected printer

[LagoST]

The printer always shows as offline or unable to contact. I have tried resetting the printers on the Mac as suggested in one of the posts and now when I try to add the printer I get the error message above.

Hi @LagoST

Welcome to the HP Support Community. I'd be happy to assist you.

Let us try these steps:

1.) Remove All Barriers: Certain building materials can get in the way of weaker signals like Bluetooth. Metal, bulletproof glass, concrete, and plaster are particularly bad, and marble, plaster and brick aren’t great easy. So if you’re really struggling with interference, your first step should be to move your Bluetooth devices away from these materials. That means no brick walls between you and your devices, and definitely no metal desks! 

  

2.) Change Router Channel: If you have an Apple router and you’re constantly getting interference with your WiFi, try rebooting it. Upon restart, the station will search for a new channel. Specifically, a different channel than the one your Bluetooth devices is using to communicate. If you don’t have an Apple router, you may need to instead go into your router settings and try changing the channel manually. Experiment with different channels to see which one works best. 

  

3.) Move Closer to Your Router: If you often find that you’re getting interference when talking on a wireless headset while on a WiFi call (you’ll know because you’ll hear static), try moving closer to your router. This will give you a more robust WiFi connection, so the Bluetooth frequency can’t overpower it. 

  

4.) Get Away From Microwaves and Fluorescent Lighting: Both emit frequencies of 2.4GHz, and moving away from them will distance you from the source. 

• Also, check with your Internet service provider if your router is able to forward 'Bonjour packets'.

Restart the Wireless router, the printer, and the MAC

Update the printer firmware

Click here to download and install the latest firmware from your computer.

On the printer, go to Setup > Network > Restore network settings

Go back to Network >Wireless > Wireless setup wizard and select your network.

• Make sure the printer and the MAC are connected to the same wireless network.
• Either 2.4GHz or 5GHz network.
• If you have a Dual-band router and both 2.4GHz and 5GHz networks share the same name/SSID, the printer will not be able to connect to the network. In this case, contact your Internet service provider to assign different names to both the networks.

Hope this helps! Keep me posted.
