Lexmark Printer Issue After Windows Update: Why It Happens and How to Fix It

Everything was fine yesterday, and now your Lexmark printer won't print, shows as offline, or has vanished from the printer list entirely, right after Windows installed an update. That timing isn't a coincidence. Windows updates routinely touch print drivers, the print spooler, and permission settings, and any one of those can knock a working Lexmark printer offline. Here's what's actually going on and how to get it printing again.

Why This Happens

A Windows update doesn't touch your printer directly, it touches the software Windows uses to talk to it, and that's usually where things break. A few common culprits:

• The update replaced or corrupted your driver. Windows sometimes swaps in its own generic driver during an update instead of keeping the Lexmark-specific one, and the generic version doesn't always support every feature your model needs.
• The print spooler got stuck. The spooler is the background service that manages every print job. If it was mid-job when the update restarted your PC, it can crash or hang on restart.
• Windows now blocks non-admin driver installs. Following a 2021 security fix for a Windows Print Spooler vulnerability known as PrintNightmare, Microsoft changed the default so that installing or updating a printer driver over a network connection requires administrator rights. If you're on a standard (non-admin) account, this alone can stop a driver update cold.
• A leftover, mismatched driver is conflicting with the new one. This is especially common after a Windows 10 to Windows 11 upgrade, since Windows 11 is stricter about driver signing than Windows 10 was.

Fix 1: Restart the Print Spooler and Clear the Queue

Start here before touching drivers. This alone fixes the issue for a lot of people.

1. Press Windows key + R, type services.msc, and press Enter.
2. Scroll down to Print Spooler, right-click it, and choose Stop.
3. Open File Explorer and go to C:\Windows\System32\spool\PRINTERS.
4. Delete everything inside that folder. These are stuck print jobs, not system files, so it's safe.
5. Go back to Services, right-click Print Spooler again, and choose Start.
6. Try printing a test page.

Fix 2: Run the Windows Printer Troubleshooter

Windows has a built-in tool that checks printer connections, drivers, and services in one pass.

1. Open Settings and go to System > Troubleshoot > Other troubleshooters.
2. Find Printer and click Run.
3. Let it scan and apply any fixes it finds, then restart your PC.

(On older versions, this lives in Control Panel > Troubleshooting > Hardware and Sound > Printer.)

Fix 3: Reinstall the Correct Lexmark Driver

If the spooler restart didn't fix it, the driver itself is likely the problem.

1. Press Windows key + R, type appwiz.cpl, and press Enter to open Programs and Features.
2. Find any Lexmark software or driver package, select it, and click Uninstall.
3. Open Settings > Bluetooth & devices > Printers & scanners, select your Lexmark printer, and click Remove device.
4. Go to Lexmark's official drivers and downloads page and search by your exact model number, not just "Lexmark," since drivers aren't interchangeable across models.
5. Download the driver listed for your specific version of Windows, install it, and restart your computer.
6. Go back to Printers & scanners, click Add device, and select your Lexmark printer when it appears.

If you manage more than one Lexmark printer, Lexmark also offers a Universal Print Driver, a single driver built to work across most of their mono and color laser models instead of installing a separate one for each device.

Fix 4: Clear the "Administrator Permission Required" Block

If Windows won't let you add or update your Lexmark printer and asks for administrator credentials you don't have, this isn't a bug, it's a deliberate security setting. Since 2021, Windows has required admin rights to install a printer driver over a network or shared connection by default, to close off a vulnerability attackers were using to push malicious drivers through print servers.

• On a personal computer: sign in with (or ask whoever set up the PC to use) the administrator account when the prompt appears, then complete the driver install.
• On a work or school computer: this is usually set by IT policy. Ask your IT admin to install the driver once, or to adjust the Point and Print Restrictions policy on their end. It's not something a standard user account can safely bypass.
