Hello there, I had the same problem.
My windows 11 has been updated and my Epson TM-T20III printer stops working. I tried to remove all drivers for Epson and install the new one, but that wasn't the solution. After many many hours of crossing the web and i find solution for my problem.
Check the Print Spooler Service.
Here are the steps on how to check if the print spooler service is running or not.
Step 1: Press the Windows key and type services on the keyboard.
Step 2: Select the Services app from the search results.
Step 3: Once the Services app window opens, find the Print spooler service at the bottom of the list of services.
Step 4: Now right-click on the Print spooler service and click on Restart
After that right click and select Properties from the context menu.
Step 5: In the Print Spooler Properties window, make sure the General tab is selected.
Step 6: Then select Automatic from the dropdown list of Startup type option and click the Start button below it.
Step 7: This starts the Print spooler service on the system and once it is started, click Apply and OK.
Step 8: Close the services app window.
The next step is where my problem is solved !!!
Step 9: Next, open the run box by pressing the Windows and R keys together.
Step 10: Type C:\WINDOWS\system32\spool\PRINTERSin the run command box’s textbox and press Enter key.
Step 11: This opens the PRINTERS folder on the system.
NOTE – Before opening the folder, it might prompt to accept the admin permission window.
Step 12: Now clear this folder by selecting all the files present in the folder and deleting them.
Step 13: Once done, close the folder and other windows that are open and restart the system.
Good luck!
