Ubuntu – Authentication required to modify a printer- what’s the password


I have 12.04 and have 2 printers installed, both wirelessly over my personal network, no printer sharing. When I try to modify the printers I get a window asking for authentication (username and password). For the life of me I cannot think what these might be. At first I thought it might be my Ubuntu account username and password, but I can't get it to work. The printer username and password (admin and access) doesn't work either.

Does anyone know what it is asking for, and how I can turn that off?

Many thanks.

You might be affected by this bug.

Try running

gksudo system-config-printer

in a terminal window, then setting up the printer

However, if gksudo is not found, try:

sudo -H system-config-printer
