To reinstall your HP printer, you should first completely uninstall the existing printer software and drivers, then download and install the latest software for your specific printer model.

Here are the complete steps:

1. **Uninstall the printer and software:**
– In Windows, open **Programs and Features**, find your HP printer software, and select **Uninstall**.
– Open **Devices and Printers**, find your HP printer, right-click it, and choose **Remove device**.
– Press **Windows Key + R**, type `printui.exe /s`, and click OK. Go to the **Drivers** tab, select any HP printer drivers listed, and click **Remove**. Repeat to remove all instances.
– Apply changes and close the windows.
– Restart your computer to ensure all components are fully removed[2].

2. **Download and install the latest software and drivers:**
– Go to the HP Customer Support website for Software and Driver Downloads.
– Enter your printer’s exact model name or number to find the correct drivers.
– Download and install the recommended software, such as the HP Smart app, which facilitates setup and printing[1][3].

3. **Optional: Update firmware and BIOS**
– For best performance, check for and install the latest printer firmware updates on the HP site.
– Also update your PC’s BIOS if advised, as outdated BIOS can interfere with drivers[1].

This process ensures a fresh installation and resolves common issues. Restarting your PC after uninstalling and after installing drivers helps the changes take effect properly[2][4].

If you want a quick reinstall without fully uninstalling, you can also try removing and re-adding the printer via **Windows Settings**, but the full uninstall method recommended above is more thorough[4].
