Kodak Drivers
When you installed the Kodak printer drivers did you use the troubleshooter and compatibility program in Windows 7? If not uninstall the drivers than reboot and then reinstall them using compatibility for what ever operating system that your Kodak printer worked with. I imagine since you are using a Kodak you have Vista installed.
Remember this is a RC and drivers are not made yet for it so you have to use compatibility mode in windows 7.
