Welcome to the HP support community.

 

I understand that you want to downgrade the ink cartridges, I am glad to assist you.

There is no option to downgrade the printer firmware.

It is not recommended to use third-party cartridges for better print quality.

Refer to this HP document for further assistance:- Click here

 

Keep me posted

If this helps, please mark the public post as an accepted solution so that it benefits several others.
