You connect it to the hub the same way you do the systems; with a patch cable. Then, the printer will have to be configured for your network, IP address, subnet mask, gateway. This may be through the printer itself with some type of menu setup, or it may allow browser access. You may also need some type of utility software installed on the systems, especially Win98.
The alternative would be to simply hook the unit up to one of the systems via the parallel cable, install the drivers and map it.
