Hi @JoeB4444, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
The B8450128 error code on your HP OfficeJet Pro 8028 indicates a firmware or hardware failure that caused the printer to stop working mid-print job. Here are some troubleshooting steps to try:

1. Power Cycle the Printer

>Turn off the printer.

>Unplug the power cable from both the printer and the wall outlet.

>Wait 2-3 minutes.

>Plug the power cable directly into a wall outlet (avoid power strips).

>Turn on the printer and check if the error persists.

2. Perform a Semi-Full Reset

This resets the printer to factory defaults and can resolve firmware glitches.

>Turn off the printer.

>Press and hold the Back (⟲) and Home (🏠) buttons simultaneously.

>While holding the buttons, turn the printer back on.

>Release the buttons when the Reset Menu appears.

>Use the arrows to select Semi-Full Reset and confirm.

3. Update the Printer Firmware

If the printer starts working after a restart, update the firmware to prevent future issues:

>Go to HP Support → Search for "OfficeJet Pro 8028 Firmware."

>Download and install the latest firmware update.

4. Reinstall Printer Drivers (If Needed)

If the error occurred while printing from a computer:

>Uninstall HP Smart and drivers from your PC.

>Restart your PC.

>Download the latest drivers from the HP Support website.

>Reinstall and test printing.

5. Check for Hardware Failures

If the error persists, it might indicate a hardware failure (such as a corrupted board or failing printhead).

I hope this helps. 

Take care and have a good day.
