What I meant was that this forum where you have posted this message is for
Microsoft Office topics. Networking computers isn't really part of Microsoft
Office.
That said, in Windows, the "workgroup" is the way to let computers on the
same network see each other. For example, if each computer on the same
network (your home broadband or wi-fi network) has the same "workgroup"
setting, such as HOME or SPARKY, then they will be able to see each other
and share files and printers located on each computer.
A printer could be shared in this way if it is connected to one of the
computers in the workgroup. Then the other computers in the workgroup can
see that printer, as long as the computer connected to the printer is
powered on.
If that's not enough info, try the Windows help, try a Google search for how
to network Windows computers in a workgroup, or try posting to one of the
Windows or networking forums.
