I have to print through a Samba server sharing an HP printer. After upgrading to 12.04 I'm no longer able to get it to work.
The printer is shared through a samba server and I need to provide logon info (domain, username and password).
The machine that I'm having trouble with is a fresh install of Ubuntu 12.04 64 bit. As a measure to troubleshoot, I created a fresh install of ubuntu 10.04 32 bit as a virtual box image on the Ubuntu 12.04 64 bit machine and had no trouble getting it to print.
I suspect authentication to be the problem. Any idea as to what is wrong? Any suggestions how to make further troubleshooting? Any information I should provide to enable you to help me?
EDIT: To be more specific, when I want to add a network printer I do this through the GUI and when I need to input credentials it will not verify me (although this works fine on the virtual box).
Print dialog. As username I input domain/username.
If I choose "Prompt user if authentication is required" and then press verify it prompts me for credentials(username, domain and password). If I input username as: domain/username, let domain be empty and supply a password it is able to verify everything. This is the only way that I have made it to verify credentials on Ubuntu 12.04. This however doesn't make me able to print.
