On my fresh install of Ubuntu 9.10, the printer management was not working.
When I opened system->printers, it was not connected. When I pressed connect, it gave an httpconnectionencryption message.
Some help bug files mentioned printer sharing, and editing the config file.
I found that my config files were blank.
I reinstalled through Software Center, but it turns out, that's only the gui.
I reinstalled Cups through the System -> Synaptic Package Manager, and now it is working.
