If you bought a new HP printer and are trying to download printer drivers on your computer, then 123.hp.com/setup is your answer. You just need to visit the HP setup link and from there you can download the printer software and drivers compatible with your device. But before you do so, make sure you have a stable internet connection and your HP printer is switched on. Also, you should set up your printer machine first and bring it in a ready state before downloading printer drivers or connecting it with the PC.
