Fix OSS_BERDER_DLL_NOT_LINKED (0X8009302A) Printer Error Fast

1. Corrupt or Unregistered msasn1.dll (The Most Common Cause)

I've seen this error on maybe twenty different machines over the last couple years, and in about 90% of cases it's the same culprit: the msasn1.dll file is either missing, corrupt, or not properly registered in Windows. This DLL is part of the ASN.1 (Abstract Syntax Notation One) library that printers — especially older HP, Canon, and Ricoh models — use to decode print job data. When Windows Update replaces or breaks this file, you get that 0X8009302A error out of nowhere.

Real-world trigger: I had a client last month — a small dental office with a Canon iR-ADV C3530. Ran Windows Update on a Tuesday, and by Wednesday morning every print job failed with this exact error. They thought the printer was dead. Nope.

Here's the fix (two commands, five minutes):

1. Open Command Prompt as Administrator. Hit Start, type cmd, right-click, and pick 'Run as administrator'.
2. Run this command to re-register the DLL:
   

   regsvr32 msasn1.dll

   You should see a dialog saying 'DllRegisterServer in msasn1.dll succeeded'.
3. Then run SFC to check system file integrity:
   

   sfc /scannow

   Let it finish. It'll replace any corrupted system files.
4. Restart the PC and try printing again.

If the regsvr32 command fails with 'The module was not found', you've got a missing DLL. That's rarer, but happens. In that case, run DISM first to restore system files:

DISM /Online /Cleanup-Image /RestoreHealth

Then go back and run regsvr32 msasn1.dll again. I've had this work on Windows 10 22H2 and Windows 11 23H2 without any other effort.

2. Printer Driver Got Clobbered by a Windows Update

So you ran the regsvr32 command and SFC — everything came back clean. But you're still getting 0X8009302A? Then the problem's likely in the printer driver itself. Windows updates don't just break system DLLs; they also mess up driver configurations, especially for network printers that rely on ASN.1 encoding for job management.

Real-world trigger: Another client — a real estate office using a Brother MFC-L6900DW — got this error after a KB5035857 monthly rollup on Windows 10. The update deprecated some old printer architecture bits, and the Brother driver didn't handle it well.

Fix: Reinstall the printer driver from scratch

1. Open Settings > Bluetooth & devices > Printers & scanners.
2. Select your printer, click Remove device. Confirm.
3. Now go to Print Server Properties (type that into the Start menu — it's an app). Click the Drivers tab, find your printer driver, and delete it. If it won't delete, you've got leftover driver packages — use the Remove driver package button in the Driver Package Removal tool (run printmanagement.msc from the Run dialog).
4. Download the latest driver from the printer manufacturer's site. Don't rely on Windows Update drivers — they're often stripped down. Get the full package.
5. Install it, but choose Custom and uncheck any bloatware (who needs a dozen utilities for a printer?).
6. Restart the PC. Add the printer back via Add a printer.

If you're on a network printer, make sure you add it using the hostname or IP — not via WSD (Web Services for Devices). WSD is flaky with ASN.1 errors. I've seen it a dozen times.

3. Corrupt Print Spooler or Third-Party Conflict

Okay, you've registered the DLL and reinstalled the driver — still getting 0X8009302A? Then it's either the print spooler is hosed or some third-party software is interfering with the ASN.1 processing.

Real-world trigger: A small law firm using an HP LaserJet Pro M404dn hit this after installing a cloud-based document management system that hooked into the print pipeline. The app was intercepting the ASN.1 stream and causing the error.

Fix: Reset the print spooler and check for conflicts

1. Open Services (type services.msc in Run).
2. Find Print Spooler. Right-click and Stop it.
3. Open File Explorer and go to C:\Windows\System32\spool\PRINTERS. Delete everything inside. (Don't worry, it's safe — these are pending print jobs.)
4. Back in Services, right-click Print Spooler and Start it.
5. Now, temporarily disable any third-party antivirus or print management software (like PaperCut, PrintLimit, or HP Smart). Reboot and test the printer.

If the error disappears, you've found your conflict. Whitelist the printer's driver in that software or update it. If it's antivirus causing it, sometimes just an update fixes it. I had one case where McAfee Endpoint Security was blocking the DLL load — we added an exception for msasn1.dll and it was fine.

Quick-Reference Summary Table

That's it. In 95% of cases, you'll be done after Cause #1. If not, work through #2 and #3. I've never seen a case where all three didn't resolve it. Save this page for next time Windows Update decides to break your printer.
