Ethernet Networking- P7:One of the biggest problems when discussing networking is knowing where to start. The subject of computer networks is one of those areas for which you have to "know everything to do anything." Usually, the easiest way to ease into the topic is to begin with some basic networking terminology and then look at exactly what it means when we use the word Ethernet. | 168 Network Servers Files the Web and Printers Shared Printer Architectures There is more than one way to connect a printer to a network Connect a printer to a desktop computer and share that computer with other users. Connect a printer to a server and use that computer as a print sever. Connect a printer to the network perhaps with a stand-alone print server as an intermediary. Why do you need a print server Because a printer is much slower than the network. Users can send print jobs to the printer much faster than the printer can print them. The solution to traffic jams on the way to the printer is print spooling a technique in which the print server places copies of the print jobs on disk in a waiting area known as a print queue. A print server is software running either on a computer or on a small stand-alone device that manages the print queue. It takes care of adding jobs to the queue sending them to the printer as the printer becomes available and providing an interface for a system administrator to manage the queue. The last printing option a stand-alone print server is the easiest to install and maintain. The printer server which is usually no bigger than an eight-port unmanaged switch attaches between the printer and the network. You then configure each workstation that will use the network-attached printer. Windows machines typically need to have a printer driver installed before searching the network for the printer Mac OS X machines usually won t need a driver but will still need to search the network to recognize and add the printer. The print-server has enough intelligence to accept print jobs from across the network. It requires no maintenance. Occasional Printer Sharing If you have printer that needs to be shared infrequently then you may want to attach that printer to a workstation and share that printer through the workstation rather than through a print server. To make it happen the owner of the workstation has to turn on the printer sharing .
