HP Smart error - printer offline

[Lucky66Vette]

I have an HP OfficeJet Pro 6978 All-in-One printer. My desktop is an HP Pavilion All-in-One 27. Keeping it real within the HP family, right? Running Windows 11 for Home version 22H2. I use my home Wi-Fi for network connectivity to support printing from my desktop and mobile devices on my home Wi-Fi network.   I have had this setup for years with no problem. Today, my HP Smart app stopped recognizing the correct status of my printer. I can print over the network from my desktop to the OfficeJet as I always have in the past. But if I try to scan a document on the printer using the HP Smart app, the app indicates the printer is off-line and must be "turned on" in order to work. But the printer is powered on, and the status in Microsoft Home control panel shows "ready" and I can print from the desktop over the Wi-Fi network to the printer. So the problem appears to be with the HP Smart app. I have reset the printer Wi-Fi network several times, made sure the printer and desktop were using the same Wi-Fi network, and successfully set up the Wi-Fi direct using the code from the printer. I printed the Printer Satus Report from the OfficeJet and it indicates network status as "Ready," yet the HP Smart App still thinks the printer is powered off and off-line.

Suggestions?

Hi @Lucky66Vette,

Welcome to the HP Support Community. 

I'd like to help!

Printer Software – Uninstall Existing Software (Optional)

If the software is already installed and you want (need) to uninstall it:

Control Panel > icon view > Programs and Features >

Scroll down, click, and Uninstall the software

After the software is removed, Restart the computer and log in

Install full-feature software from here

• After the software is installed, Restart the computer and log in.
• Look for the Printer Assistant shortcut icon on your Desktop named for your printer.
• The printer software works with your other programs on the computer to provide print service.

For Example, printer software works with Office programs, with your PDF Reader software, with your browser, and with your photo printing / editing software.

Reminder

If there is both printer software and a printer Firmware update, install the Full Feature Software, Restart the computer and log in, then consider updating the printer firmware.  If there are instructions on the Firmware Details page, please read and follow these instructions to properly install the Firmware.

Open the Windows Store to find and download the HP Smart Application.
