OfficeJet Pro 6978
macOS 10.15 Catalina

My All in One OfficeJet Pro 6978 shows white screen after printing and shows offline. I have to unplug each time. I'm an InstantInk subscriber and assume that an update is causing this issue? Been happening about 2 weeks. Using MacOS 10.15 Catalina.

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

 

I understand the printer goes offline. Let us try these steps:

 

Update the printer firmware

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

Click here to know different methods of updating printer firmware.

 

Also, check for any software updates on Mac

Click the Apple icon > About This Mac > Software Update and install any available update.

 

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.
  • The wireless status menu on your Mac should also give us quite a lot of information that would help us identify the issue. You can press and hold the option key on your keyboard and click the WiFi icon to get detailed information.
  • 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.

 

Hope this helps! Keep me posted.
