A print server can refer to two different options- an actual server that shares out many different printers from a central administration point, or a small dedicated box that allows a legacy printer to connect to a network jack. A network attached printer on the other hand has a network card built into it, and thus has no need for the latter option. It can still benefit from the former however, as network attached printers are extremely useful in a corporate environment since they do not require the printer to be connected directly to a single user’s system.
