To set up an HP printer, follow these general steps:

1. **Unpack and prepare the printer**
Remove all packaging materials, install ink cartridges, and load paper into the tray.

2. **Power on the printer**
Make sure the printer is plugged in and turned on.

3. **Connect the printer to your network**
For wireless setup, place the printer near your Wi-Fi router. On the printer’s control panel, access the Setup, Network, or Wireless settings menu, then select the Wireless Setup Wizard to find and connect to your Wi-Fi network[5].

4. **Install printer software or HP Smart app**
On your computer or mobile device, download and install the HP Smart app or the printer drivers from HP’s official site at 123.hp.com. Follow the prompts in the software or app to complete setup[3][4].

5. **Add the printer to your computer or device**
On Windows or Mac, go to your system settings or control panel, find “Printers” or “Devices,” and choose to add a new printer. Select your HP printer from the list and complete the installation[2].

6. **Print a test page**
Once installed, print a test page to confirm the printer is working correctly.

For a more detailed wireless setup, there are step-by-step video guides available that show how to connect HP DeskJet printers to Wi-Fi and install the driver software using HP Smart[1].

These steps cover most HP printer models and will vary slightly depending on the specific model and whether you use USB or network connection methods. Always refer to the printer’s manual or HP Support online for model-specific instructions.
