To set up an HP printer, first ensure the printer is powered on and connected (via USB or Wi-Fi). Then download the latest printer software and drivers from the official HP support website by entering your printer model[1][4]. For wireless printers, connect the printer to your Wi-Fi network using either the printer’s control panel or the HP Smart app, available for Windows, macOS, Android, and iOS[2][3]. Run the downloaded software and follow the on-screen instructions to complete installation, selecting the correct connection type when prompted[4].

Key steps for HP printer setup:

– **Power on the printer** and place it near your computer or router.
– **Uninstall old HP printer software** if present to avoid conflicts[4].
– **Download and install the latest drivers** and software from HP’s official site (support.hp.com or 123.hp.com)[1][3][4].
– **For wireless setup**, use the printer’s screen or the HP Smart app to connect the printer to your Wi-Fi network[2][3].
– **Run the installation software**, follow instructions, and connect the printer via USB or wireless as prompted[1][4].
– **Print a test page** to confirm the setup was successful[4].

For some HP printers, you can also update firmware via software for improved performance[1]. If using Windows, you can update printer drivers through Windows Update or Device Manager[1]. For macOS, the printer can sometimes be set up using built-in drivers[1].

If you prefer video guidance, HP provides step-by-step setup tutorials on YouTube showing wireless setup and software installation for specific models like HP Deskjet series[2][5].

If you encounter OS compatibility issues, check the HP Smart app or support site for supported platforms[3].
