To set up your HP printer using the “hp com 123 setup” process, go to the official website 123.hp.com/setup. From there, follow the guided steps to download and run the HP Easy Start software or the HP Smart app, which will walk you through the installation and connection process, including connecting the printer to your Wi-Fi network or setting up a USB connection[1][5].

Key points for the setup:
– Make sure your printer is powered on.
– Use HP Easy Start or HP Smart software as prompted.
– For wireless setup, ensure your computer or mobile device is connected to the same Wi-Fi network you want your printer to use[3].
– If issues arise, such as the software not downloading or the printer not being detected, troubleshoot by restarting devices, restoring Wi-Fi settings on the printer, and ensuring no guest or public networks are interfering[2][3].
– For scanning or firmware updates, you may also be prompted to go to 123.hp.com to install updates or drivers[4].

If you encounter difficulties, HP’s official support community and help documents can assist with troubleshooting errors during setup[1][3].
