I recently purchased a Nikon Coolpix 4300 camera and downloaded some pictures utilizing a USB connection. That worked perfectly, but upon trying to print a document, I got the error, "Driver file has been corrupted". and the printer was no longer available. As I've been using the printer on one USB port for over 2 years with no issues, I have to assume that the problem is a result of using the other USB port with the camera. Is there any incompatability with thee 2 devices?
