Hi Lưu Thanh,
Thank you for reaching out to Microsoft Q&A forum. I understand how frustrating it is when printing suddenly stops working, especially when Windows shows “No printer installed” even though the printer appears during setup.
Let’s go through the steps below together:
Step 1: Restart the Windows Print Spooler
Windows sometimes detects the printer but gets stuck during the final setup. Restarting the Print Spooler refreshes the printing system.
- Press Windows + R on your keyboard
- Type services.msc and press Enter
- In the list, find Print Spooler
- Right‑click Print Spooler then select Restart
- Close the window and try printing again
This clears incomplete printer installations and resets Windows’ internal print queue.
Step 2: Remove any incomplete printer entries
Windows 11 may leave a “ghost” printer that prevents proper installation.
- Open Settings
- Go to Bluetooth & devices > Printers & scanners
- If you see the printer listed:
- Click the printer name
- Select Remove device
- Restart your computer
- Return to Printers & scanners and click Add device
This removes partially installed drivers that can cause the “Access denied” or “No printer installed” message.
Step 3: Check Windows Protected Print Mode
Windows 11 may block printers that require traditional drivers.
- Go to Settings > Bluetooth & devices > Printers & scanners
- Scroll down to Printer preferences
- Look for Windows Protected Print Mode
- If it shows Turn Off, click it and confirm
- If this option is locked, the device is managed by an administrator
Additionally, if your computer is managed by your company (work email, device policies, admin restrictions), Windows 11 may require administrator approval to install printers.
In this situation, Windows is blocking the printer driver for security reasons. To move forward, your IT team will need to approve or install the printer driver and allow printer installation through their security policies. Once that’s done, the printer should install normally.
To help me guide this the right way, could you share a bit more detail?
- Is this a personal computer or a work‑managed device?
- How is the printer connected - USB or network/Wi‑Fi?
- What’s the printer brand and model?
With that information, I can point you to the quickest next step.
