well, let's say I solved it with a workaround However: 1. configuring from YaST Printers didn't work, for me 2. Google Chrome + CUPS WEB does not show the request for the root password 3. my workaround is Firefox + cups web I don't know if it can actually be considered closed, but I find it's hard to verify because the YaST GUI gave me problems... So, if you want closed... for me it's ok
