My printer lights on the cover, are constantly flashing blue and yellow, when i attempt to print, it says it's offline, but then prints, I can't scan at all, and I thought i saw there was an update that said these color codes are changing... it could be three different problems or it could one problem all be wrapped up in one update. I can't find where I would go for updates. I have the HP ENVY Pro 6400 series PCL-3
Thoughts?

Please look at page 8 of this manual and try to identify the exact color codes.
I recommend the printer be connected directly to the modem instead of WiFi direct mode. A network report will show which mode you are in.
Possibly the printer takes a long time to wake up from sleep.
Set sleep to off or never if possible.
Scanner may need full feature software.
Full feature software April 2024
