mac not recognizing hp envy 7640

[KLPART]

I may use the wrong terminology here -- I had my WIFI hardwired throughout the house. There are white puck-like disks by UniFi in various rooms, which hand off to each other so the wifi works everywhere. Now my Mac doesn't see the printer (HP Envy 7640) unless it's in the same room. Previously, when we just had wireless plug-in disks (from Comcast) I could print from everywhere. Does anyone know why it wouldn't be working now?

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

It seems like you are using WiFi Extenders.

Check if these are configured in Bridge mode. Check with your Internet service provider.

Which version of macOS are you using?

• 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

Hope this helps! Let me know how it goes.
