It’s not straightforward to get everything working. You not need an account. But if you follow instructions
HP fouls you to do so.
And if you bought an e-printer (which you don’t see upfront as it’s mentioned nowhere) you have to be very careful as HP deliberately tries to push you into buying/ singing up for their ink subscription!
Once done, you cannot ever cancel or go back!
Printer itself works fine. Good prints and scans. Even without using the app or other HP software.
But this idiotic tricks to get your data, push subscriptions, make printers not work with 3rd party toners ensure this is my last HP printer.
