The system configuration printer finds the proper driver and then asks for a login-password

Hi everyone,
I'm reinstalling my PC under bunsenlabs (release Carbon) and thus using the SCP release 1.5.18.
I've installed HPLIP release 3.22.10. The SCP starts all right, asks for the admin password and then detects my network printer (an HP Photosmart 2575). HPLIP finds the driver all right but then pops up an authentication dialog asking for a login and password. So far I had never been asked for that and I don't think my printer needs it. No local menu on the printer deal with credentials ! Something must be going wrong. I don't have any idea how to investigate this. Do you ? Regards

Let's add that the authentication dialog appears whatever the way of connection : HPLIP, JetDirect via DNS-SD or HP JetDirect. So HPLIP doesn't seem to be the cause, but rather the SCP.
