Hi
Regular Scanners are Not Network Devices Native to Windows and thus can not be shared
while attached to a computer.
You need to buy a Scanner that is Network capable; such a scanner is plugged directly to
a Network port, and can be shred by all the computers on the Network.
Brothers Brand has sub $200 "All in One " units that includes a scanner and it is
Network enabled. Other Brands have similar Hardware. Network Scanners are usually geared
toward Office use and thus they are more expensive than regular scanners.
There is software that can make a regular scanner Network able. Unfortunately this
software is expensive to the extend that you are better of buying a New Network Capable
scanner.
