Check the manual for your scanner - most scanners sold for use in homes and
small offices don't support network sharing. Scanning is more interactive than
printing; you have to load the scanner with the documents to be scanned, so why
walk over to the scanner, load the documents for scanning, then walk back to a
distant computer to do the scanning?
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

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
