Linker error for imported header file Xcode 4.5

Question

I have downloaded a header file and static library file (.a file) from the internet. They are provided by the wireless printer which i bought for my iphone and trying to make print functionality working in my app. The problem is when I run the sample app provided by them to test printer, I get the following linker error...Obviously the app was designed in the previous versions of Xcode and Im using Xcode 4.5. Much appreciated if someone could Guide me..

If you are building an iOS project and it's using the i386 architecture, then you must be building for the simulator. What happens when you build for an actual iOS device?

It's possible that the library was compiled only for the processor architectures for real iOS devices, typically armv6, armv7, or armv7s. You can use the file command in Terminal to see what architectures are in the .a library file.
