After following directions for set-up we tried to print and printer did not seem to connect.  Hazard sign on the print page.   Perhaps the computer is looking for the old printer?

@JJ9000, Welcome to the HP Support Community! I’m here to help.

I understand you are trying to print wireless from the Mac. The new printer has to be connected to the mac in order to do so.

To connect the printer to the network, follow the steps mentioned in this document - Connecting an HP Printer Using Wi-Fi Protected Setup (WPS)

• Restart the router, the printer, and the Mac
• 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

Perform a ping test to check the connectivity

1. Obtain the IP address of the printer by printing a network configuration report

2. Touch and hold the Information button  for 3 seconds.

   All the control panel buttons light up.

3. At the same time, touch the Information and Resume buttons .

   A Wireless Network Test Results page prints.

4. Open a new Terminal window (it's located in Applications > Utilities, or you can just start typing it in Spotlight).
5. Enter “ping” followed by the IP address of the printer. 
6. Press Return. Press ctrl C after 10 pings
7. There should be 0% packet loss, share the results in your next post.

You may use the HP Smart app to print or the AirPrint driver.

Hope this helps! Let me know how it goes.
