Windows 7 print spooler service keeps being turn off.

Hi,

Have you installed the latest printer drivers from the printer manufacturer’s website?

Was the printer working fine before?

Did you make any software or hardware changes to the computer before this issue started?

This behavior occurs if existed printer drivers are corrupt.

I suggest that you remove all the installed printers and reinstall the Windows 7 printer drivers if available.

 Remove a printer

1. Click the "Start" button, type PRINTER in the search box and press Enter.

2. Find the icons of installed printers, and delete them.

3. Right-click on the blank part of the window, and choose "Run as administrator"->"Server Properties".

4. On the Drivers tab, select the listed printers and click the Remove button. Please then select Remove driver and driver package.

5. Open Start menu, input APPWIZ.CPL in the Search box and press ENTER to launch "Programs and Features".

6. Try to remove all related printer software.

If the issue is not resolved, I suggest that you clear the printing sub system.

Step 1

======

Start Windows Explorer, and then rename all files and folders in the following two folders:

c:\windows\system32\spool\drivers\w32x86

To rename a file, we can right click the file and select Rename.
