Let's talk about sharing a USB scanner over network, LAN or wireless. I will borrow an example from my recent guide on sharing a USB printer: there are two Windows machines — one is in my home office upstairs, the other one is in a room downstairs, they need shared access to a USB scanner.
The PC upstairs has Lexmark 3500-4500 Series device connected to it via USB cable. I have a Wi-Fi router and wireless network, and I am to figure out various ways of sharing the scanner.
The free subscription - FlexiShare allows only to send invites to your local devices, you won't have an opportunity to access remote ones. To share and access your scanner you need to acquire a paid FlexiHub subscription.
Windows OS offers functionality to share a scanner with other computers, or set it up as a wireless scanner on your network.
Plug in your scanner’s USB cable to a computer connected to the network or to the USB port of a router or modem. Follow the instructions to install the scanner, if it has not been done before. You can refer to the installation instructions specific to your scanner model or Microsoft guide.
Open Control Panel from Start menu, go to Network and Sharing Center and click View network computers and devices.
Right-click your scanner icon and select Install to make it accessible to other machines in the network.
This does not work on Windows XP, there is no such option. To share printer on Windows XP try either of the above methods.
As you see, FlexiHub seems to be the easiest way to share the printer over the network. You don’t need any additional settings or hardware — just the single point access from the FlexiHub account.
