What is a role of print server ?

A print server is a computer system which is directly connected to a local Printer. All the print request on the network send to the printer are routed through the print server. In modern printers (LAN printer) which are directly connected to the switch no specilised print server is required rather each machine on the network servers as a print server. 

Print server is a server that manage one printer in a network or more with all its functions plus manage other print servers.

A print server arrange the data that is supposed to go to different printers. The printers cannot handle the files which come so fast one after another so here the print server queues the files locally to be processed when the printer is ready to accept files. Print servers may support a variety of industry-standard or proprietary printing protocols including Internet Printing Protocol, Line Printer Daemon protocol, NetWare,NetBIOS/NetBEUI, or JetDirect.

A print server is a software application, network device or computer that manages print requests and makes printer queue status information available to end users and network administrators. Print servers are used in both large enterprise and small or home office (SOHO) networks.
