HP OfficeJet Pro 6978 All-in-One Printer

[Ulumma]

Since I moved I have not been able to print. I have downloaded the latest software on the hp website and even bought a printer cable and I keep getting the error message, "some of the software for printer is missing. Please contact the printer's manufacturer for latest compatible software." It is very frustrating. My operating system is macOS Monterey 12.1. Please help...

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

I see that you are not able to print from the Mac. Is the printer connected via a USB cable?

Make sure the cable is directly connected between the Mac and the printer.

The use of a USB hub is not recommended. Also, make sure the cable is connected to a USB 2.0 port on your Mac.

Do you have an Anti-virus/firewall installed on the Mac? If yes, disable the same for time being.

To check, select the Go menu on the top of the screen and go to the Applications folder.

• Check if the printer is getting recognized by your Mac:

1. From the Apple menu, choose About This Mac.
2. Click System Report.
3. Under the Hardware heading on the left side of the System Information window, click USB.

USB 3 devices appear under USB 3.0 Bus, and USB 2 devices appear under USB 2.0 Bus.

Update the printer firmware
