About the fix :
As the name implies, it helped me to get the printer working, but was not the
right/best way to do it.
As I never used CUPS before (no need in squeeze !), I was confused when it was
asking for username/password.
I entered the name of the user for which I wanted print capability. Which was
refused because not in lpadmin. And thus the mail "fixed : added lpadmin"
I should have logged as root and then add the printer !
So I thing there is no need to insert the first user in the lpadmin group, as
C. Perrier objected/stated.
However, there is a regression in wheezy as plug and play printing is no longer
working as it used in squeeze !
I made some tests with debian 6(live-gnome) and 7 (testing-xfce).
