I need to upgrade my firmware to install new HP 11 printheads. I downloaded the software to install frimware package A.05.01, but there is a warning that the installed frimware must be A.02.06 or greater. I currently have frimware A.02.02.  The executable says to contact HP Support.  Can I use HP11 Printheads dated June 2020 without the upgrade?  Or can I upgrade from A.02.02 without harming something? Or can I get a firmware upgrade from A02.02 to anything A.02.06 or greater?
