What is a print server? 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.

What is a print server? A print server, or printer server, is a device

that connects printers to client computers over a network. It accepts print jobs from the computers and sends the jobs to the appropriate printers, queuing the jobs locally to accommodate the fact that work may arrive more quickly than the printer can actually handle.

What is a print server? Ancillary functions include the ability to

inspect the queue of jobs to be processed, the ability to reorder or delete waiting print jobs, or the ability to do various kinds of accounting (such as counting pages, which may involve reading data generated by the printer(s)).

What is a print server? A print server may be a networked computer

with one or more shared printers. Alternatively a print server may be a dedicated device on the network, with connections to the LAN and one or more printers.

What is a print server? Dedicated server appliances tend to be fairly

simple in both configuration and features. Print server functionality may be integrated with other devices such as a wireless router, a firewall, or both. A printer may have a built-in print server.

What is a print server? Print servers are used in both large

enterprise and small or home office ( SOHO ) networks.

In a large organization, a single dedicated computer serving as a print server might manage hundreds of printers.

What is a print server? In a small office, a print server is often a

specialized plug-in board or small network device about the size of a hub that performs the same function as a dedicated print server, but frees up valuable disk space on the office's limited number of computers.

Printing Protocol Print servers may support a variety of

industry-standard or proprietary printing protocols including Internet Printing Protocol Line Printer Daemon protocol

Internet Printing Protocol (IPP) The Internet Printing Protocol (IPP) provides

a standard network protocol for remote printing as well as for managing print jobs, media size, resolution, and so forth.

Internet Printing Protocol (IPP) Like all IP-based protocols, IPP can run

locally or over the Internet. Supports

access control, authentication, and encryption, making it a much more capable and secure

printing solution than older ones(LDP).

Internet Printing Protocol (IPP)

IPP allows a client to: query a printer's capabilities submit print jobs to a printer query the status of a printer query the status of one or more print jobs cancel previously submitted jobs

Internet Printing Protocol (IPP) IPP uses TCP with port 631 as its well-known

port. Other IPP implementations also use UDP

with port 631 for IPP printer discovery.

Line Printer Daemon protocol The Line Printer Daemon protocol/Line

Printer Remote protocol (or LPD, LPR) is a network protocol for submitting print jobs to a remote printer.

A server for the LPD protocol listens for requests on TCP port 515

Line Printer Daemon protocol An LPD printer is identified by the IP

address of the server machine and the queue name on that machine.

Line Printer Daemon protocol A printer that supports LPD/LPR is sometimes

referred to as a "TCP/IP printer" (TCP/IP is used to establish connections between printers and clients on a network), although that term would be equally applicable to a printer that supports the Internet Printing Protocol.

What is a network printer? A networked printer is a printer that is

hooked up to your computer network with a network cable or with a wireless networking adapter. Networked printers have what is called a print server attached to them.

Setting-up a Network Printer

A class of printers, often called network printers , are specifically designed for connecting directly to a computer network. Larger businesses have for a long time integrated these printers into their company networks for their employees to share.

Setting-up a Network Printer

Network printers for home and small businesses look similar to other types but feature an Ethernet port , while many newer models incorporate built-in Wi-Fi wireless capability. To configure these kinds of printers for networking:

a. Update the printer’s settings (such as WPA wireless encryption keys or DHCP addressing) as needed to join the local network.

b. For Ethernet capable printers, connect the printer to a network router using an Ethernet cable.

c. For Wi-Fi capable printers, associate the printer with a wireless router or other wireless access point.

Setting-up a Network Printer

All modern versions of Windows include a feature called File and Printer Sharing for Microsoft Networks that allows a printer connected to one PC to be shared with other PCs on a local network. This method requires the printer be actively connected to the PC, and that computer be running so that other devices can reach the printer through it. To network a printer via this method

Setting-up a Network Printer

1. Enable sharing on the computer. From within the Network and Sharing Center of Control Panel, choose “Change advanced system settings” from the left-hand menu and set the option to “Turn on file and printer sharing.”

2. Share the printer. Choose the Devices and Printers option on the Start menu, select the “Printer properties” after right-clicking on the target computer, and check the “Share this printer” box within the Sharing tab.

Setting-up a Network Printer Printers can be installed on a PC via Devices

and Printers. Some printers when purchased also come with software utilities (either on CD-ROM or downloadable from the Web) intended to help simplify the installation process, but these are generally optional. Microsoft Windows 7 added a new feature called HomeGroup that includes support for networking a printer as well as sharing files.

Setting up a Network Printer

To use a homegroup for sharing a printer, create one via the HomeGroup option on Control Panel, ensure the Printers setting is enabled (for sharing), and join other PCs to the group appropriately. The feature works only among those Windows PCs joined into a homegroup enabled for printer sharing.

Setting up a Network Printer

Operating systems other than Windows incorporate slightly different methods to support network printing:

1. Older versions of Mac OS X provided a utility called Print Center for setting up printers connected to Mac computers. Current versions added the ability to automatically detect and add certain kinds of printers, with manual configuration options in the Print & Fax section of System Preferences.

Setting up a Network Printer

2. Apple AirPrint enables Wi-Fi wireless printing capability on Apple iOS devices including the iPhone and iPad. AirPrint support requires using a specially manufactured printer of the same brand.

3. Different flavors of Unix/Linux each provide generic support for network printing. User interface details differ but most are based on a common Unix printing mechanism

Wireless Print Servers Many older printers connect to other devices

via USB but do not have Ethernet or Wi-Fi support. A wireless print server is a special-purpose gadget that bridges these printers to a wireless home network . To use wireless print servers, plug the printer into the server’s USB port and connect the print server to a wireless router or access point .

Using Bluetooth Printers Some home printers offer Bluetooth network

capability, usually enabled by an attached adapter rather than being built in. Bluetooth printers are designed to support general-purpose printing from cell phones. Because it is a short-range wireless protocol, phones running Bluetooth must be placed in close proximity to the printer for the operation to work.

Printing From the Cloud Cloud printing provides the ability to

wirelessly send jobs from Internet-connected computers and phones to a remote printer. This requires the printer be networked to the Internet and also involves special-purpose software.

Printing From the Cloud Google Cloud Print is one type of cloud

printing system, popular especially with Android phones. Using Google Cloud Print requires either a specially manufactured Google Cloud Print ready printer, or a computer networked to the network printer running the Google Cloud Print Connector software.
