4. Select Uninstall

Step 2: Reinstall HP Smart App.

1. Download the HP Smart app from 123.hp.com (Android, Apple iOS, iPad OS), 

or HP Smart - Microsoft Store (Windows), 

or HP Smart - Mac App Store (Mac).

3. The app searches for recently installed printers.

- If your printer displays, click it. If you are setting up a new printer, it might display with Set-Up under the name.

- If your printer does not display, click the Plus sign, and then follow the on-screen prompts to add your printer or set up the printer.
