Hi. I'm David, and I'm happy to help you.
To enable the scanning functionality for your HP Envy 6155 on Windows 11, you will need to install the full driver and software package from the manufacturer.
Please download and install the "HP Easy Start Printer Setup Software (Internet connection required for driver installation)" directly from the official HP support website:
https://support.hp.com/us-en/drivers/hp-envy-6100-all-in-one-printer-series/model/2103462278
Once the download is complete, double-click the file to run the installer and follow the on-screen instructions. This process will install the necessary utility, which allows you to utilize the scanner features both from your computer and via the physical controls on your printer.
If you encounter any errors while trying to run the installer, let me know.
Feel free to ask any questions you may have.
