Unable to install Full Webpack Software for Officejet 6812

[Richstan06]

I have tried several times to install the Full Webpack Software for the Officejet 6812 All-in-one printer. I also tried the suggestions that HP gave inside the help section of the installation package. Each time it gets to installing the printer on the network but cannot install because it says it cannot connect to the printer via the network. I have checked the network settings on both computer and printer. The IP address matches, the subnet matches, the printer status is connected. I turned off the firewall also to no avail. Restarted the printer and computer several times, I even uninstalled the printer and reinstalled it to be sure that was not the issue. I don't know what else to do. Please advise.

Welcome to the HP User Community.

The printer software is supported in Windows 11.

There might be pieces of printer software stuck and left over from previous installation attempts.

If the pieces can be found and removed, this might help the software to install.

If you have not done so,

Restart everything, including the Router, Printer(s), Computer(s), and other devices that use the network.

Next,

Optimally, you need only complete the following:

• Check the Security software that it is not in some way infringing on your printer software.
• Uninstall the printer software from Programs and Features

NOTE - Add the steps in this section

In the case of "really stuck" software, it might be best - or even necessary - to add the steps in the Check and Remove section

Next,

• Restart the computer and log in
• Install a fresh copy of the Full Driver
• Finally, if you have not already done so, Get and install the HP Smart application
