Microsoft Deprecates LPR/LPD: Transitioning to Modern Printing Solutions

Microsoft has issued a reminder that the longstanding Line Printer Daemon (LPR/LPD) protocol is on its way out. In a move that highlights its commitment to modernizing network printing, Microsoft plans to deprecate this legacy printing method over the next few months. This announcement is especially significant for users relying on older UNIX-based printing solutions as well as mixed-platform environments.
In this article, we’ll break down what LPR/LPD is, why its removal is imminent, what alternatives are available, and how you can prepare your environment for a seamless transition.

Understanding LPR/LPD: A Legacy Protocol​

What is LPR/LPD?​

The Line Printer Daemon protocol (LPR/LPD) is one of the oldest methods for sending print jobs over a network. It has been a staple in UNIX and mixed-OS environments for decades. Originally designed in an era when network security and encryption were less of a priority, LPR/LPD enabled computers to deliver print jobs to a print server with minimal overhead. However, as technology advanced and security concerns grew, newer printing protocols emerged that offered enhanced features, security, and efficiency.

Historical Context​

• Introduction in Early Unix Environments: LPR/LPD has been around since the early days of UNIX, forming a reliable, albeit archaic, solution for network printing.
• Windows Server Adoption: Even though Windows Server 2012 marked the beginning of its deprecation, many organizations continued to rely on LPR/LPD due to legacy compatibility and familiarity.
• Modern Requirements: With increased concerns over network security and performance, newer protocols such as the Internet Printing Protocol (IPP) and enhanced printing solutions on modern Windows platforms have become more attractive.

Summary: LPR/LPD served its purpose in an earlier era, but modern network security and improved technology have rendered it obsolete. Microsoft’s decision aligns with the broader trend of phasing out outdated protocols in favor of robust, secure solutions.

The Deprecation Announcement: What’s Changing?​

Microsoft’s Official Reminder​

Microsoft’s recent announcement serves as a timely reminder that LPR/LPD, already marked as outdated in Windows Server 2012, will soon be completely removed in upcoming releases. Although an exact date for deprecation has not been specified, the communication indicates that the removal is expected within the next few months.

What Does Deprecation Mean?​

• Phasing Out Support: While current systems may still operate using LPR/LPD, future updates and releases will no longer support this protocol.
• Impact on UNIX Clients: Computers running UNIX or UNIX-based systems that have traditionally depended on LPR/LPD will lose the ability to print via this method.
• Mixed-Platform Repercussions: Environments that rely on legacy printing protocols, especially in mixed operating system settings, need to urgently evaluate their printing configurations.

Key Takeaways:

• Microsoft is pushing for modernization by phasing out outdated protocols.
• The deprecation affects primarily UNIX-based systems, though mixed environments could see broader implications.
• Users need to explore alternative protocols to ensure uninterrupted printing functionality.

Modern Alternatives: Transitioning from LPR/LPD​

For UNIX and Cross-Platform Environments – Embrace IPP​

The Internet Printing Protocol (IPP) is the recommended alternative for systems that currently rely on LPR/LPD. IPP offers several modern features:

• Enhanced Security: IPP provides improved encryption and authentication methods, safeguarding print jobs and communications.
• Better Error Handling: With modern protocols, error reporting and troubleshooting are more efficient, reducing downtime.
• Wide Compatibility: IPP is widely supported across different platforms, making it ideal for mixed-OS environments.

Transition Steps for UNIX Users:​

• Verify IPP Support: Check with your printer manufacturers or software vendors to ensure that your printers and print servers support IPP.
• Update Your Configuration: Modify your printing settings or scripts to point to IPP endpoints instead of LPR/LPD.
• Test the New Setup: Run a series of test prints to confirm that IPP is functioning correctly and that all previous functionality has been successfully replicated.
• Plan for Gradual Migration: If you operate a large print network, consider a phased transition to IPP to minimize disruptions.

For Windows Clients – Continue Using the Windows Standard Port Monitor​

Windows computers that connect to UNIX shared printers are not left without options. Microsoft recommends using the Windows Standard Port Monitor, which remains compatible with UNIX printing frameworks while leveraging newer printing technology.

Steps for Windows Administrators:​

• Review Printer Configurations: Ensure that your Windows clients are set up to use the Windows Standard Port Monitor in scenarios involving UNIX shared printers.
• Consult Documentation: Familiarize yourself with Microsoft’s documentation on configuring print services to avoid compatibility issues.
• Monitor for Updates: Stay updated on Microsoft’s official communications regarding the removal timeline and technical guidance.

Brief Summary:

• UNIX Users: Transition to IPP for a secure, efficient printing solution.
• Windows Users: Rely on the Windows Standard Port Monitor to maintain connectivity with UNIX shared printers.

Broader Implications and Industry Trends​

Microsoft’s Strategy of Modernization​

The move to deprecate LPR/LPD is part of a broader strategy by Microsoft to eliminate obsolete protocols and technologies across its product lines. Similar trends have been observed in other areas:

• Exchange Server Support: As detailed in our End of Support for Exchange 2016/2019: Key Risks & Migration Strategies, legacy systems are being phased out in favor of more secure and modern solutions.
• Privacy and Security Upgrades: Recent changes in Windows 11, such as the removal of certain legacy features for enhanced privacy, underline Microsoft’s commitment to keeping systems secure and efficient.

Lessons from the Past: Why Deprecation is Inevitable​

Organizations that delay updating their infrastructure often face:

• Security Vulnerabilities: Outdated protocols like LPR/LPD may harbor unpatched vulnerabilities, exposing networks to potential threats.
• Operational Incompatibilities: As support for legacy systems dwindles, day-to-day operations can suffer from unexpected disruptions.
• Increased Technical Debt: Maintaining outdated systems can incur additional costs and require workaround solutions that are neither efficient nor sustainable.

Real-World Impact: A Case Study Approach​

Imagine an organization that manages a diverse fleet of UNIX and Windows systems across multiple departments. For years, they relied on LPR/LPD to handle print jobs from legacy UNIX systems to centralized print servers. With Microsoft’s announcement, IT administrators now face the challenge of migrating to IPP—a process that involves:

• Reconfiguring print servers and endpoints.
• Training staff on the new protocol.
• Testing extensively to ensure that all printers function properly during the transition.

While this might sound like a significant undertaking, the long-term benefits—improved security, better performance, and reduced technical debt—outweigh the initial migration effort.
Key Insights:

• Modernization is crucial for sustaining business operations and security.
• Transitioning protocols now can prevent unexpected disruptions later.
• A structured, phased approach to migration will ensure continuity during the shift.
