My laptop was reformatted, from Windows to openSUSE 12.1. My problem is that I'm new to Linux and don't have much technical expertise of solving problems in installation of programs, printers etc...
Can any one help me how to install the printer?
There is a configuration tool in openSUSE called YaST, which can be used to configure various aspects of the system, including printers (amongst many other things).
There is a wikipage which should help you with configuring the printer using YaST printer module. If it does not, please let us know what exactly does not work so that will be hopefully able to help you.
