Hi, I'm a British freelance web developer and IT consultant. I've been building, repairing and servicing desktop, laptop and mobile devices (both personally and professionally) for over 10 years now. I'd really appreciate being able to speak with you further about this project. If I understand your problem with this particular Windows 7 machine, you're unable to view any devices under Devices and Printers, even though there is a printer connected and working. I have a couple of methods that should resolve this issue. I look forward to hearing from you, and hope you have a great day!
