For peer-to-peer printing (where each computer prints directly to the
network printer), run the installer (as in step 3) on each computer.
For client/server printing (where each computer sends print jobs
through a network server computer), you need run the installer only on the
server, and set up the server for printer sharing. Then each client computer
must install the printer driver and connect to the shared printer on the
network server. (An easy way to do this is to use the Microsoft Windows
Point and Print function. See your operating system documentation for
details on Point and Print.)
For basic information on peer-to-peer and client/server printing, see the
Network Basics Tutorial on the HP Jetdirect CD.
