To set up an HP printer, go to the official HP setup website at 123.hp.com/setup or install the HP Smart app on your computer or mobile device. Then, follow the on-screen instructions to install the printer drivers and software, connect the printer to your wireless network or via USB cable, and complete the configuration process.
Key steps include powering on your printer, downloading and installing the HP Smart app or setup software from 123.hp.com/setup, putting the printer into wireless setup mode (usually by pressing the Wi-Fi button for several seconds), and selecting your printer from the app or software so it can connect to your network. If the printer is not found wirelessly, you may be prompted to temporarily connect it to your computer with a USB cable to complete installation, after which you can remove the cable and print wirelessly ([1](https://sites.google.com/site/hpcomprinterkeycode/), [2](https://www.youtube.com/watch?v=NIrnwz4Xtss), [4](https://123.hp.com)).
The HP Smart app is available for Windows, macOS, and mobile devices and provides a streamlined setup experience with network connection and driver installation in a few easy steps ([4](https://123.hp.com), [2](https://www.youtube.com/watch?v=NIrnwz4Xtss)). For specific printer models like DeskJet or OfficeJet, you can also find model-specific setup guides and drivers on 123.hp.com/setup ([3](https://www.youtube.com/watch?v=lpB4j1Az940)).
If any issues occur, consult the printer’s manual or HP Support for troubleshooting help.
