Resolve Windows 10 related issues for your HP computers or printers by HP Windows 10 Support Center
The Printer reports A 5 to the mobile device, but it is A 4. Can't change it.
Welcome to the HP Support Community.
Could you check if the same happens on any other mobile?
Let's try to reset the Printer here:
Reset the product
Also, try connecting the Printer to a different wall outlet directly.
Meanwhile also try a firmware update: https://support.hp.com/in-en/document/ish_1776648-1643972-16
