In Financial Dept; it has two PC. They want to using printer. But My Chief, he want to restrict for them to use Internet. Reasons was "The Finance Dept; Data are really case sensitive and confidential " so that he don't want another problem via network. I mean I want to set two printers for them (2 PC) private using. They don't want to link the computer to another department as well. If I link with default USB cable only one computer can be printing. If I Using Network cable to connect via Switch/Router the internet connection is enable. So How can I do for this ?
