I see that the latest version of software for the 8600 All in one printer is using HP Smart.

[Back9TypeGuy7]

How do I get rid of older versions of HP software so I can install HP Smart as my only printer software.  Is there an HP app to remove that old software as it is not nearly as good as HP Smart???  I know cause I have only HP Smart on my Lenovo laptop and it works perfectly.

The standard Full Feature Software and HP Smart are different enough that having one installed does not preclude having the other.  That is, you can install HP Smart without removing the Full Feature Software.

If you wish to remove the printer Full Feature Software, you may do so.

NOTE:

The sections marked with "**" are optional checkpoints to make sure the printer software is "gone". 

Uninstall Existing Printer Software

Uninstall existing printer software from Programs and Features

Method One - Control Panel > icon view > Programs and Features >

Method Two - Settings > Apps > Apps and Features >

Search or Scroll down

Uninstall the printer software

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

If printer software will not uninstall, appears to be removed and then shows up again, or is otherwise not “going away” when you tell it to do so, try an Uninstaller program.
