To set up the scanning feature for your HP printer (such as a 123 HP setup scanner), you need to install the full-feature HP printer software, connect the printer to your computer (usually via Wi-Fi), and configure scan-to-computer settings either through the HP Smart app or the HP Universal Scan software.

Here is a step-by-step overview:

1. **Install full-feature HP software**: Download and install the complete HP driver and software package from the official HP website, or use HP Easy Start to ensure scanning functions are installed properly[2][5].

2. **Connect your printer to the same network**: Ensure your printer is connected to your wireless network and your computer is on the same network[3].

3. **Set up Scan to Computer**:
– Use the HP Smart app or full HP Scan app on your computer to configure scan destinations.
– Optionally create a separate Windows user profile with a password for scan folders to increase security[1].
– Specify the folder on your PC where scans will be saved.
– Make sure to enter your network credentials for the scan folder if required[1].

4. **Test scanning**: Use the printer’s control panel or HP software to scan a document and verify it saves correctly to your PC[3][5].

Additional tips if you face scanning errors directing you to “123.hp.com”:
– Ensure all printer drivers and HP software are updated to the latest versions[4].
– Restart both printer and computer if scanning fails[4].
– Run “HP Print and Scan Doctor,” a diagnostic tool available from HP, to fix common scan issues[4].
– Reinstall the HP software if scanning is still not working properly[4].

If you want a guided tutorial, there are videos like the one published in May 2024 which show complete scanning setup and wireless connection steps for HP printers[3].

In summary, visit the official HP support site or use the HP Smart app to download software and follow the instructions to connect and set up the scanning function fully on your PC—this is often all that is needed for the “123.hp.com/setup scanner” process. The “123.hp.com” URL usually directs users to this setup and software download page.
