I am not able to scan from my laptop. I can't download HP scan twain or any other scanning software. I am wireless connected and can print from my laptop, but when I try to scan from my computer's scanning program, it says that it can't finde any devices. Please help...

Hi @amanda2606

Welcome to the HP Support Community. I'd be happy to assist you with the scanning issue. 

Download and install HP Print and Scan Doctor, it is a Windows tool to fix printer issues. 

If the issue still persists, try re-installing the printer driver -

1. In the search box, type and open "Uninstall a Program".

2. Look for HP Printer software.

3. Right-click to uninstall.

4. In the search box, type and open “Devices and printers”.

5. In the Devices and Printers, look for your HP printer. If you see it listed right-click on it and choose “Delete” or “Remove Device”.

6. Open the run command with the "Windows key + R" key combo. 

7. Type printui.exe /s and click Ok. (Note: there is a space in between “printui.exe” and “/s”).

8. Click on the "Drivers" tab.

9. Look for HP Printer driver. If you see it Click on it and click “Remove” at the bottom.

10. Select Ok.

11. Select Apply and Ok on the Print Server Properties windows.

12. Close Devices and Printers Once the software and drivers are removed.

13. Restart the computer.

14. Download and install the software and drivers from here for Windows 8.1 (64-bit).

15. Click on the downloaded file and follow the on-screen instructions.
