Try the following steps to clear Printer Spooler files and enable the spooler service and check if it helps:

b. Double-click "Printer Spooler" in the Services list.
c. Click Stop and click OK.
d. Click Start, type "%WINDIR%\system32\spool\printers" in the open window, and delete all files in this folder.
e. Now restart the Print Spooler service and check.
Note: Make sure you have created a System restore point before trying these steps.
