I recently purchased a printer of HP Company as I need better printer for my office which would provide me an economical printing. I am having windows 7 operating system installed on all of my office computers. I connected the printer to the computer and have also installed HP solution center. So the problem is that when I open the solution center then it displays that my printer is disconnected, but as far as I know it is connected, so why is it displaying such message. Please provide information on the same.
