This article understands why a print server is required or not when a network printer is available. The main functionality of a print server is to convert a USB or parallel port printer into a network printer. The print server converts the parallel or USB port on a non network printer into a network port. Normal printers do not have network ports due to which an additional device like a print server which is capable of converting the printer to a network port printer is required. For normal printers to work as a network printer, it has to be shared using Windows printer sharing feature. To conclude, if you have a network printer a printer server is not required as it already would have a network port associated with it.
