Hi @Colton15,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

The error code UA_400_EB000U0422 you're encountering while setting up your printer suggests there is an issue related to either the printer’s software, connectivity, or a potential problem with the device’s communication with your system or network.

Here's a step-by-step approach to troubleshoot and fix this error:

1. Check Printer Connection

The error code could be triggered by issues with the printer’s connection, whether wired or wireless.

• For a wireless connection: Ensure the printer is properly connected to your Wi-Fi network.
  • On the printer’s control panel, check the wireless settings to confirm it's connected to the correct network.
  • Make sure your Wi-Fi router is functioning correctly and that other devices can connect to the network.
• For a USB connection: If you are using a USB cable to connect the printer to your computer, try the following:
  • Unplug and plug the USB cable into a different port on your computer.
  • Check the USB cable for damage or try a different cable if possible.

2. Update Printer Drivers

An outdated or corrupted driver could be causing the issue. It’s a good idea to update or reinstall the printer drivers.

• Go to the HP Support website and search for your printer model (e.g., HP DeskJet 2021).
• Download and install the latest driver for your printer.

Alternatively:

• You can use Windows Device Manager to update your printer’s driver:
  • Right-click on the Start button and select Device Manager.Expand the Printers section and find your printer.
  • Right-click your printer and select Update driver.
  • Choose Search automatically for updated driver software.

3. Reset the Printer

If the error persists, it may help to reset the printer to its default settings.

• Power off the printer, then unplug the power cord from the outlet.Wait for about 30 seconds, then plug it back in and turn the printer on again.
• This can help resolve issues caused by temporary glitches or settings errors.

4. Reinstall the Printer

Uninstall and then reinstall the printer on your computer to eliminate any conflicts between the printer and the system.

• Go to Control Panel → Devices and Printers.Right-click your printer and select Remove device.
• After removal, reinstall the printer by either using the installation CD (if you have it) or by downloading the latest software from the HP website.

5. Check for Firmware Updates

Sometimes a printer’s firmware needs to be updated for it to work properly, especially if the printer is a bit older.

• Visit the HP website for your printer’s model and look for available firmware updates.
• If available, follow the instructions to download and install the latest firmware for your printer.

I hope this helps.
