Microsoft has quietly rolled out a subtle but significant change in the latest Windows 11 non-security update, build 22631.4534 (KB5044384), that adds a printer compatibility badge in the Settings app. This small icon—a shield with a green checkmark—appears under the printer’s name in the Bluetooth & devices > Printers & scanners section, indicating whether the device supports Windows Protected Print Mode (WPP) and the Internet Printing Protocol (IPP). The update, released as an optional preview on October 22, 2024, for Windows 11 23H2 and 22H2, might fly under the radar for most users. But for IT administrators and security-conscious consumers, it marks a pivotal moment in Microsoft’s slow-burn campaign to overhaul Windows printing security.

The badge itself is not just a cosmetic tweak. It surfaces a long-running architectural shift that began with Windows 10 and gained momentum after the infamous PrintNightmare vulnerability spree of 2021. With PrintNightmare and its many variants, attackers exploited legacy print spooler code to gain SYSTEM-level privileges on vulnerable machines. Microsoft’s response was twofold: a series of emergency out-of-band patches and a long-term plan to retire the ancient v3 printer driver model in favor of a sandboxed, modern print stack. The new badge brings that plan right into the user interface, making printer security posture visible at a glance.

What the Badge Actually Shows

When you navigate to Settings > Bluetooth & devices > Printers & scanners and select an installed printer, Windows now checks two things. First, it verifies that the printer uses IPP (Internet Printing Protocol), the modern network printing standard that communicates over HTTP/HTTPS. Second, it confirms that the printer supports Windows Protected Print Mode, a security-hardened printing pipeline that isolates print jobs in a restricted AppContainer sandbox. If both conditions are met, a small green shield with a checkmark appears, accompanied by the text “This printer is compatible with Windows protected print mode.”

If the printer fails either check, the badge does not appear. In some cases, a warning may surface if WPP is enabled on the system but the printer cannot comply. This visual feedback finally gives non-technical users a way to assess whether their hardware meets the new security standard without digging into event logs or device manager properties.

Microsoft has been moving toward mandatory IPP since Windows 10 21H2, where it introduced the IPP Class Driver (previously known as the Microsoft IPP Class Driver) as the default for network printers. The idea is to kill off the bloated, kernel-mode v3 printer drivers that rely on fragile vendor-specific code. By shifting to user-mode, AppContainer-isolated print components, the attack surface shrinks dramatically. Even if an attacker compromises a print job, they are trapped inside a low-privilege container and cannot escalate to SYSTEM.

Windows Protected Print Mode: A Deep Dive

Windows Protected Print Mode (WPP) is the keystone of this initiative. It is an optional feature that users or administrators can enable manually. When turned on, WPP enforces three hard rules:

  • Only IPP-based printers are allowed. Legacy printers using USB or older network protocols (such as TCP/IP raw port 9100 or WSD) are blocked unless they can be natively translated to IPP.
  • All print jobs go through a strict AppContainer sandbox. The spooler process, previously a prime target for privilege escalation, runs with minimal rights.
  • Third-party print drivers are forbidden. Only inbox Windows IPP class drivers or certified Microsoft IPP drivers are permitted.

Once WPP is active, any printer that does not meet these criteria simply stops working. The new badge now allows users to check compatibility before flipping that switch, avoiding the frustration of suddenly non-functional printers. This is especially useful in enterprise environments where IT staff plan staged rollouts of WPP.

WPP is not enabled by default in Windows 11 23H2 or 22H2. Users must go to Settings > Bluetooth & devices > Printers & scanners > Windows protected print mode and toggle it on. The badge serves as a pre-flight check. Microsoft has stated that WPP will eventually become the default for all Windows editions, though no firm deadline has been announced. The rumors point to Windows 11 24H2 as a potential inflection point, but official documentation remains coy.

IPP: The Protocol Behind the Shield

The Internet Printing Protocol (IPP) isn’t new. It dates back to the late 1990s and underpins nearly every network printer today, whether you realize it or not. When you print from a smartphone via AirPrint or Mopria, you’re using IPP. Modern printers advertise themselves on the network via IPP over HTTP/HTTPS, often with zero-configuration discovery through WS-Discovery or mDNS. Windows’ built-in IPP Class Driver handles these printers seamlessly, eliminating the need to hunt down obscure driver packages from vendor websites.

What makes IPP critical for WPP is its stateless, HTTP-based nature. Unlike the old raw socket or LPR/LPD protocols, IPP works within the browser-grade sandboxing already built into Windows. The IPP printing pathway runs inside the same user-mode AppContainer used for Edge tabs or PDF rendering, so it inherits the same exploit mitigations. Print jobs are submitted via MIME-encoded HTTP requests, which Microsoft’s modern print stack can parse, render, and forward without ever touching a kernel-mode driver.

Not all IPP printers are created equal, though. The badge considers whether the printer fully implements the IPP Everywhere standard or the Microsoft IPP extension set required for WPP. If a printer advertises IPP but lacks support for certain mandatory operations (like Validate-Job or Get-Printer-Attributes with specific tags), compatibility may fail. The badge takes that into account, sparing users from partial support that could break after enabling WPP.

The Gamepad Keyboard and Other Update Goodies

Build KB5044384 isn’t just about printers. The same update introduces a new virtual keyboard layout optimized for gamepads. Dubbed the “Gamepad keyboard” in the touch keyboard settings, it allows users to type using an Xbox controller. Keys are arranged radially or in a grid that maps intuitively to controller buttons and thumbsticks. This feature targets handheld gaming PCs like the ASUS ROG Ally and Lenovo Legion Go, which run Windows 11 and often need text input during gaming sessions. It also benefits cloud gaming scenarios where a full keyboard isn’t available.

Other fixes and enhancements include:

  • An updated Open With dialog that respects user preferences for default apps more reliably.
  • A fix for the File Explorer crash that occurred when navigating to Home.
  • Resolved an issue where Windows Update would reinstall an already-installed driver.
  • Updated the Windows Kernel Vulnerable Driver Blocklist to prevent known malicious drivers from loading.
  • Various performance improvements for Bluetooth audio and Wi-Fi connectivity.

None of these individually move the needle, but together they show Microsoft’s continued commitment to polishing the Windows 11 experience outside the headline feature drops. The printer badge, however, stands out because it ties directly to a long-term security overhaul.

How to Check Your Printer for Compatibility

If you’ve installed KB5044384, verifying your printer’s WPP compatibility is trivial:

  1. Open Settings and go to Bluetooth & devices > Printers & scanners.
  2. Click on your printer. Its properties page opens.
  3. Look for a green shield icon and the text “This printer is compatible with Windows protected print mode” below the printer name. If you don’t see it, the printer fails one of the checks.

For network printers that don’t show the badge, there may be steps you can take:

  • Ensure the printer firmware is up to date. Many vendors have released IPP Everywhere firmware updates to align with Microsoft’s requirements.
  • Check that the printer is installed via IPP and not a legacy TCP/IP port. Remove the printer and re-add it using the “Add device” button, which prefers IPP discovery.
  • If the printer is connected via USB, it may not support IPP over USB (a niche feature). Consider connecting it via network if possible, or wait for a vendor driver supporting WPP.

Enterprises can audit their fleet with PowerShell. The Get-Printer cmdlet now exposes a “CompatibleWithWPP” property when run on updated clients. For a quick scan:

Get-Printer | Select Name, ComputerName, Type, CompatibleWithWPP

This empowers IT teams to inventory which printers will survive the transition to WPP.

The Road to a Driverless Future

Microsoft’s endgame is a “driverless” printing ecosystem. The v4 driver model introduced in Windows 8/8.1 was a step toward user-mode only print drivers, but it still allowed third-party code. WPP closes that loophole entirely. In the future, all printing on Windows will flow through the Microsoft IPP Class Driver or certified store apps that provide print workflows, much like the modern print dialog in Windows Photos or Edge.

HP, Canon, and Epson have already signaled support. HP’s Universal Print Driver (UPD) has an IPP Everywhere mode, and its newer printers ship with IPP enabled out of the box. Canon’s imageRUNNER ADVANCE series supports the full IPP stack. Epson’s WorkForce Enterprise line has added IPP over USB for direct-attached security. The printer badge will help consumers and businesses identify these compliant models.

For older printers, however, the writing is on the wall. Printers that rely on proprietary drivers, especially those for specialized functions like large-format or POS receipt printing, may never be compatible with WPP. Organizations clinging to these devices will face a hard choice: replace the hardware or forego WPP’s security benefits—and accept the risk of continued kernel-mode driver vulnerabilities.

Why This Matters Now

Printer security remains a sore point. The Cybersecurity and Infrastructure Security Agency (CISA) added the PrintNightmare family to its Known Exploited Vulnerabilities catalog, mandating federal agencies to patch or mitigate promptly. Even now, months after the patches, researchers continue to find ways to bypass restrictions, often by chaining print spooler flaws with other bugs. WPP is the nuclear option—it eliminates the spooler’s privileged components altogether.

But adoption has been slow. WPP first appeared in Windows 11 22H2 as an optional, well-hidden feature. The new badge and its prominent placement in Settings lower the barrier to entry. For the first time, a non-technical user can see that their printer is “secure” or not, and perhaps prompt them to upgrade their decade-old inkjet.

Microsoft’s decision to deliver this in a non-security preview update (often called a “C” or “D” release) is strategic. These optional updates allow enterprises and enthusiasts to test new features before they’re pushed in the next month’s Patch Tuesday. The printer badge will very likely land in the November 2024 mandatory cumulative update, reaching all Windows 11 users who install it. By then, IT shops should have their compatibility data ready.

Potential Pitfalls and User Reactions

Early feedback on forums like Reddit and Microsoft’s own Feedback Hub shows mixed sentiments. Some users celebrate the clarity the badge brings; others bemoan that their perfectly functional printers are now flagged as “incompatible” with no easy fix. HP LaserJet 1020 owners, for example, find themselves without a migration path, as that classic monochrome printer uses a proprietary communication protocol. Anecdotes also mention that even some IPP-capable printers fail the check due to incomplete IPP Everywhere implementations.

Microsoft’s response has been to work with printer OEMs to issue firmware updates. The Mopria Alliance, which drives IPP adoption, has published compliance tools that OEMs use to verify their implementations. The badge’s arrival may accelerate these updates as vendors realize customers will see a “not compatible” label and potentially return the printer.

One under-discussed angle is the impact on virtual printers, such as print-to-PDF or OneNote printers. These are typically software-only drivers that may not support IPP natively. Microsoft’s own Microsoft Print to PDF is already WPP-compatible because it is an inbox IPP provider. Third-party virtual printers will need to adapt or risk being blocked when WPP becomes mandatory.

Compatibility with Windows 11 24H2 and Beyond

Windows 11 24H2, already available in the Release Preview Channel, includes an updated kernel and system components that further harden printing. Reports indicate that WPP may be enabled by default for fresh installs of 24H2 Home and Pro editions, while Enterprise editions will have a toggle during setup. The printer badge feature is backported to 23H2 and 22H2, so it will appear there as well after the next Patch Tuesday.

Looking ahead, Microsoft’s “Windows Protected Print Mode” section in the Windows Hardware Dev Center states: “Over time, we plan to make WPP the default print mode for all Windows users, phasing out support for legacy print drivers.” The badge is the UI manifestation of that commitment, gently nudging the ecosystem toward a more secure state.

Conclusion

The printer compatibility badge might seem like a tiny addition to Windows 11’s sprawling settings maze, but it carries disproportionate weight. It transforms an obscure security feature into a user-visible attribute, making the invisible fight against printer-based attacks tangible. For the average home user, it’s a cue to check if their all-in-one printer is up to date. For the enterprise, it’s a compliance tool and a roadmap giver. And for the industry, it’s a final push toward a driverless future that has been a decade in the making.

As Windows 11 continues to evolve, expect more such badges and indicators. Security is moving from the kernel to the glass, and Microsoft isn’t shy about letting you know which devices earn the shield.
