Printer Driver Hell: Fixing ERROR_BAD_DLL_ENTRYPOINT (0X00000261)
A corrupt printer driver with a bad DLL entry point. Fix: remove the driver completely and reinstall the right one. I've seen this break entire office print queues.
You're staring at ERROR_BAD_DLL_ENTRYPOINT (0X00000261) on your printer
I know. It's frustrating. One day your printer worked, next day it's dead, and Windows throws this cryptic code at you. Let's cut through the noise and fix it.
The Fix: Nuke the driver and start fresh
Here's the deal. This error means the printer driver's DLL file has a broken or missing entry point. Windows can't load the driver's code properly. The only reliable fix is to completely remove the printer driver and reinstall the right one. Restarting the print spooler? Won't work. Registry tweaks? Waste of time.
Step 1: Remove all copies of the printer
Go to Settings > Devices > Printers & scanners. Find your printer. Click it and hit Remove device. Do this for every instance you see — sometimes Windows keeps duplicates.
Step 2: Kill the driver files manually
This is the part most people skip, and it's why the error comes back. Open PowerShell as admin and run:
Get-PrinterDriver | Where-Object {$_.Name -like "*YourPrinterModel*"} | Remove-PrinterDriverDon't know the exact name? Run Get-PrinterDriver first to list all drivers. Then target the one causing trouble. If PowerShell isn't your thing, you can also go to Print Management (type printmanagement.msc in Run), then Drivers, and delete the driver from there.
Step 3: Clean up leftover files
Head to C:\Windows\System32\spool\drivers\x64\ (or x86 if you're on 32-bit). Look for folders containing your printer's manufacturer name. Delete them. I had a client last month whose Brother driver left ghost files in 3\MachineSpecific\ that kept resurrecting the old broken driver on reboot.
Step 4: Reboot and reinstall
Restart the machine. Now go download the latest driver from the manufacturer's website — don't use Windows Update or the built-in driver. For HP, use the full solution installer (not the basic one). For Brother, grab the "full driver & software package". Run the installer, connect the printer, and test.
Why this works
That error code, 0X00000261, gets thrown when the printer driver's DLL exports a function with the wrong address or missing signature. Windows' printer driver architecture is picky — one mismatched entry point and it refuses to load the entire thing. A corrupt update, partial uninstall, or leftover junk from an old driver version is usually the culprit.
By manually wiping the driver files from the spooler folder, you eliminate any stale DLLs that Windows might cache. The fresh driver installs cleanly, and the entry points line up correctly.
Less common variations of the same problem
Network printer with redirected drivers
If you're using a shared printer from another PC, the driver on the host machine might be corrupt. Fix the host first, then reconnect from the client. Seen this on a Windows 10 Pro setup where the print server had a mismatched x64 vs x86 driver.
Print spooler crashes immediately
Sometimes the error crashes the spooler service hard. You can't even access Print Management. Boot into Safe Mode with Networking, then do Steps 2 and 3. Safe Mode loads minimal drivers, letting you bypass the broken DLL long enough to delete it.
Virtual printers (PDF, OneNote, etc.)
Less common, but I've seen it with "Microsoft Print to PDF" after a bad Windows update. The fix is the same: remove the printer, delete the driver, and run DISM /Online /Cleanup-Image /RestoreHealth to repair system files.
Third-party driver packs
Some manufacturers bundle multiple drivers into one installer (looking at you, Canon). If you install the wrong model, the DLL entry point can conflict. Always use the model-specific driver, not the universal pack.
Prevention: Keep your drivers lean
- Only install drivers for printers you're actually using. Every extra driver is a potential point of failure.
- When uninstalling a printer, always remove the driver too — don't just delete the printer device.
- Update drivers manually from the manufacturer's site. Windows Update often pushes generic drivers that can conflict.
- If you're on a network with multiple printers, use a dedicated print server (even a cheap Raspberry Pi with CUPS works) to isolate driver issues.
- Once a quarter, run the PowerShell command
Get-PrinterDriverand check for any that look orphaned or duplicated.
That's it. No registry edits, no restore points, no guessing. Remove the driver completely, install the correct one, and you're back in business. If the error still shows up after this, check for a botched Windows update — sometimes they mess with the print spooler subsystem itself.
