A print server manages print requests and printer queue status information. It connects printers to client computers over a network, accepting print jobs and sending them to the appropriate printers. Print servers support protocols like Internet Printing Protocol (IPP) and Line Printer Daemon protocol (LDP). They can be networked computers or dedicated devices. Setting up a network printer involves configuring the printer's network settings and sharing it with other devices on the network or through cloud printing.

3. 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.

4. 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.

5. 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)).

6. 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.

7. 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.

8. 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.

9. 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.

10. Printing Protocol
 Print servers may support a variety of
industry-standard or proprietary printing
protocols including
 Internet Printing Protocol
 Line Printer Daemon protocol

11. 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.

12. 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).

13. 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

14. 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.

15. 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

16. Line Printer Daemon protocol
 An LPD printer is identified by the IP
address of the server machine and the
queue name on that machine.

17. 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.

26. 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.

27. 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.

28. 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.

29. Setting-up a Network Printer
 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.

30. 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

31. 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.

32. 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.

33. 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.

34. 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.

35. 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

36. 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 .

37. 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.

38. 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.

39. 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.
