I wish I could have confidence in your interpretation of what you see. The pop-up has two blank fields. Why you maintain the default user is "root" and it needs to be changed is beyond me.
Yes, I maintain it... I don't have 2 blank fields, but 2 fields containing "root" and the registred root password Anyway, I found that there were 2 running cupsd. After killing one, everything works fine, i.e for either root or me, the password is accepted. thanks everybody for your advices. best regards, -- Pierre Frenkiel
