The LPD Print Service in Windows 11 allows the system to accept print jobs from remote computers using the LPD protocol. It is a part of Print and Document Services in Windows 11. The Line Printer Daemon (LPD) protocol is a network protocol used to submit print jobs to a remote printer. It was originally developed for Unix systems but has been widely adopted and implemented on various platforms, including Windows. Here are the steps to enable this feature in Windows 11.

Key Steps:

• Open Windows Features.
• Locate Print and Document Services.
• Expand it and enable LPD Print Service in Windows 11.

• Open Run Command and execute the following command. appwiz.cpl

appwiz.cpl

• From the left pane, click on Turn Windows Features on or off.

Turn Windows Features on or off

• Search and Locate Print and Document Services from the list of features available. Expand the Node.

Expand Print and Document Services

• Now, you can find “ LPD Print Service “. Click on the checkbox next to it, and click OK.

Enable LPD Print Service in Windows 11

• Windows will search for the required files.

Searching for Required Files

• Then, the necessary changes will be applied.

Applying Changes

• Click Restart if you are prompted to restart or click Close accordingly. However, it is suggested that the changes be restarted right away so that they will be reflected.

Close

• LPD Print Service is now enabled in Windows 11. Enjoy Cross-Platform Printing.

Infomation on the Go!

The LPD protocol facilitates the transfer of print jobs between clients and printers over a network. It is part of the Berkeley printing system and operates over TCP/IP networks. The protocol uses a client-server model where the client sends print jobs to the server (daemon), which manages the printing process.

Recommendations related to LPD Print Service:

Some formalities are to be considered after enabling the LPD Print Service in Windows 11.

Configuring Firewall Rules:

Allow LPD Service through the Firewall

To ensure proper communication, configure your firewall to allow LPD print jobs. Go to Control Panel > System and Security > Windows Defender Firewall > Allow on App through Firewall.

Setting up Automatic Startup:

Set up LPD Service Startup to Automatic

LPR Command-Line Tool:

• Windows includes the LPR command-line tool for sending print jobs to a network printer that uses LPD. This can be handy for scripting print jobs. The syntax is as follows lpr -S servername -P printername /printername /servername

Security Considerations:

• The LPD protocol was designed at a time when network security was not a primary concern. Therefore, it does not include any built-in mechanisms for authenticating clients or encrypting data , making it susceptible to unauthorized access and eavesdropping.

• Although LPD uses port 515 by default, you can configure it to use a different port if needed. This might be useful for security purposes or to avoid conflicts with other services. You can adjust firewall rules and service configurations accordingly.

• Use IPsec (Internet Protocol Security) to encrypt print jobs sent over the network. This ensures that sensitive documents are protected during transmission.

Take away:

LPD Print Service in Windows 11 is particularly useful for supporting legacy systems that do not have drivers for modern printing protocols. Many older Unix/Linux systems or applications may still rely on LPD, making it a valuable service for maintaining compatibility with these systems. Happy Printing! Peace out!
