MacBook Air will not connect with HP printer

[MariaHeys]

My MacBook Air can see the printer HP Envy Photo 6234 but will not connect. It says offline or error. Other devices print to the HP no problem so there is nothing wrong with the wireless network or printer. I had this problem before, tried everything offered in online help and fixes and eventually an HP technician had to logon and sort it for me.  It worked fine until I took my computer away with me. When I came back to the house it automatically logged on to the network no problem but will not connect to the printer. I have uninstalled printer and tried to add it again.  it tells me what it is but will not connect.  As we are now out of warranty there is a cost to having a technician sort it each time and I cannot afford the time or money to go through this process each time I take my laptop somewhere.  Any suggestions?

@MariaHeys, Welcome to the HP Support Community! I’m here to help.

I understand you are not able to print from your Mac. Let us try these steps:

• Make sure the printer and the Mac are connected to the same wireless network. Either 2.4 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 networks.
• Also, check with your Internet service provider if your router is able to forward 'Bonjour packets'.

Bonjour locates devices such as printers, other computers, and the services that those devices offer on a local network using multicast Domain Name System (mDNS) service records. The software comes built-in with Apple's macOS and iOS operating systems.

• This printer supports WPA encryption, check if the router is on the same encryption method. If using WEP or WPA-PSK+FT change it to WPA-PSK

To check the connectivity, 

1. Obtain the IP address of the printer by printing a wireless test page
2. Press and hold the Wireless button for more than 10 seconds (but less than 20 seconds). When the Ready light starts blinking, release the button.
3. Open a new Terminal window (it's located in Applications > Utilities, or you can just start typing it in Spotlight).
4. Enter “ping” followed by the IP address of the printer.
5. Press Return. Press ctrl C after 10 pings
6. There should be 0% packet loss, share the results in your next post.

Hope this helps! Let me know how it goes.
