Re: System 76 Driver (Ubuntu 13.10)
I too recently upgraded to Ubuntu 13.10. Since you are using Unity this should be no problem. Locate your Systems Settings icon - it looks like a gray gear with an open-ended wrench (spanner) lying across it at an angle. Click on the icon to open it; you should see both an icon for printers and one for power. Click the Printer icon to add your printer; click on the Power icon to adjust your power settings.
If the System 76 Driver indicates it supports only 12.10, you might want to download the latest version of the System 76 Driver from system76.com.
Hope this helps.
