Resolve Windows 10 related issues for your HP computers or printers by HP Windows 10 Support Center
I've been trying to register my new printer all day today, only to encounter a "Service Unavailable" pop-up every time.
In searching this forum regarding this problem, I see someone else had the same problem back in mid-2019.
What can be done to get this resolved?
Go to Solution.
NEVERMIND... It suddenly allowed me to register tonight!
