Hiya Jedis,
An external box, that you plug the printer into, and then plug the box into your hub?
Yep, and IMHO this is a more flexible solution. Most print servers have an internal web server for management so the new jet direct software connects to it.
but I have no idea which model to get, and what would serve my purposes for a small home network.
You can probably get the the lowest end (cheapest) model to server your needs as I don't think you would need the higher end features on a small network. I have some old 300x external ones and they still work like a charm and are a snap to configure with HP WebJet Admin.
Hope this helps some
