All printers can be connected, by USB cable, to a computer and will work without internet access. There is a trend for "Airprint" printers that can be registered and used to print from iPads, tablets & smartphones. For this to work there must be an internet connection. A printer, connected to a computer, can be used by any computer on the local network by being "Shared". Exact details of how to do this depend on which flavour of Windows you are using.
