where to type the password for printing over internet and can not install the driver on 10.10

My company has a network printer KONICA MINOLTA C353, I have added it on my Mac.

I know there is still a password needed to fill in, but I can't find where to input it.

What a bad luck is that I can install the latest driver on osx 10.10 (you can see the two disks are gray, you can install on it)
