http://localhost:631 brings me to the cups administration page. There is only a slight problem. I cannot change anything because I can't login.
When I want to change anything, it asks for username and password. I fill in my username and password of my system. After several attempts, I got locked out completely.
I tried the solution of this page:

Question: how do I login to the Cups administration page?
