I am not familiar with eAR OS (I have heard of it, but not used it), however I might be able to help. In Ubuntu, printer setup is under System > Administration > Printing, however it looks like it is done differently in eAR OS, though.
Based on screenshots (http://www.thecodingstudio.com/opens...AR%20OS%201.08
), it looks like they took the OpenSuse Control Center and modified it. I doubt that really helps you, though...
It could also help if you posted the name/model of the printer.
