When we want to connect multiple personal computers to a printer or we want to share a printer on a network, then we usually need a device referred to as a print server. Often a print server is just a computer with a number of computers shared on the network, but more often it is a dedicated device that is in itself a network device, but also connects to a number of printers.
The server acts as the interface between computer users requiring a printing service and the printers themselves. Sometimes the server is a feature or a service on another device such as a router or wireless access point. This is a good idea but does have a number of disadvantages, least of all the fact that the print server function is just another function on the router and it may not provide the same level of service as dedicated print servers do. Most servers that provide facilities for print sharing usually have a management interface that can normally be accessed over the network itself. This interface will sometimes allow the administrator of the server to set up user permissions and to set up any specific operation of the device. A client can just use a particular printer when it has been approved using some verification technique. At the point when various printers are being used, the server might be modified so that a few clients can just use specific printers whilst others may have consent to get to all printers. Having various printers joined to the print server can additionally give versatility in the occasion of a printer failing. The users can either be directed to use another printer or can manually select another printing device.
