I get the message "printer status unknown" from HP Smart app but my printer is printing fine from the web and stand-alone software; I can also check/access everything through the app. I've updated drivers, reinstalled my printer ran scan doctor and I've faithfully followed all the help files round and round. The problem persists. My older Windows 10 laptop runs the HP ....
and displays status, prints, scans, converts to PDF faultlessly I thefore tried loading the software on this laptop but, within the final furlong it comes up with 'software error' and automatically uninstaals again. It shouldn't be this difficult and, let's face it, the software is not Smart at all!

Perform root level uninstallation to remove all the printer related software's.
- In Windows, search for and open Programs and Features.
- Select your HP printer.

- In the Devices and Printers window look for your HP Printer. If you see it listed, right-click on it and choose "Delete" or "Remove Device.”
- Open up the run command with the "Windows Key + R" key combo.

Nope; that didn't work either so I did it again being especially careful to follow the instructions. There were a couple of minor issues: In Programs and Features, my printer was not listed and, in the command window, It would not allow deletion of the driver because it was 'in-use' I rebooted and the driver was successfully removed however, the Apply and OK buttons were dimmed out, so I couldn't do that.
The Full Feature Printer Installer 'PS_AIO_06_C_4700_140_408-5 was downloaded and executed but at the last hurdle it reported a Fatal Error and I followed the instructions to forward the error log to HP. The software then continued to uninstall.
I can print OK but when I try to run the solution centre, it fails because the software installation has not completed. More going round in circles? Like I said before; it shouldn't be this difficult. As retired ex IT techy, I understood this process but your average none-techy would have found it daunting at the very least.

This model printer is not compatible with the HP Smart app.
Try creating a new user account on the computer and then install the full-featured driver.
Click here to download the HP Full-featured driver.
Once downloaded, make sure to run the file to start the installation and follow the on-screen instructions.
Let me know how it goes.

Done that: same result!
"This model printer (HP Photosmart C4780) is not compatible with HP Smart app" Wow; that's a good one !!!!; it will certainly influence me should I be in the market for more hardware.
So to summarise, I have a fairly modern HP printer/scanner/copier which doesn't work with the new HP software, and the old HP software will not run on a new Laptop with the new version of Windows. Charming.........!

You can still use the Printer from the laptop without using the HP Smart App.
Let me know if this helps.
