To install a new HP printer, follow these key steps:

1. **Prepare the printer:** Unbox it, remove all packaging and protective tapes, and turn it on.

2. **Download drivers/software:** Visit the official HP website, enter your printer model, select your operating system, and download the latest drivers and software. Alternatively, Windows often provides basic HP drivers automatically via Windows Update.

3. **Connect the printer:** You can connect via USB cable or wirelessly. For wireless setup, use the printer’s Wireless Setup Wizard or Wi-Fi Protected Setup (WPS) by pressing the Wireless button on the printer and following on-screen prompts.

4. **Install the drivers/software:** Run the downloaded setup file and follow on-screen instructions. If using Windows, ensure Windows Update is set to auto-download drivers, or manually add the printer in Settings under “Add a printer” choosing network or USB connection as appropriate.

5. **Test the printer:** Print a test document to confirm successful installation.

For Mac, download the HP drivers for macOS from HP’s site and add the printer via System Preferences > Printers & Scanners after connecting to the wireless network.

Using the HP Smart app (available for Windows and Mac) can simplify wireless setup, supply monitoring, and troubleshooting.

These instructions provide a comprehensive, step-by-step approach for installing a new HP printer on Windows or Mac systems[1][2][3][5].
