The official and safe website to set up HP printers is https://123.hp.com. On this site, you can complete your printer setup by installing the HP Smart app, which is available for Windows, macOS, Android, and iOS devices. The process usually involves powering on your printer and following the instructions in the HP Smart app to connect your printer to your device and network[4].

It is important to avoid fake or scam websites that mimic 123.hp.com, as there have been reports of fraudulent sites that ask you to call support numbers or allow remote access to your computer, potentially leading to scams or malware infections[1][3]. Always verify you are on the legitimate HP site by checking the URL carefully (it should be simply “123.hp.com” with no added words or extensions) and look for the HP copyright notice on the site footer[3].

If you encounter error messages during scanning or setup that refer to 123.hp.com, it might indicate missing printer drivers or software on your computer. Installing the Full Feature HP printer software, available from the official HP support site, can resolve these issues and enable full functionality including scanning[2].
