If you have Ccleaner or Malwarebytes you can try and run them, see if you find any registry errors or malwares, you can delete them if you find any. Another thing that you could try is which would most probably fix the problem is by going to 'services'. One way of accessing the 'services' is by right clicking the task bar, then select 'start task manager', now choose the 'services' tab and then click 'services' at the bottom again which would require administrative privileges to open. Now you are inside services, next step is to locate 'print spooler' from the list. When you find it right click then go to recovery tab and check whether all three are drop boxes are set to restart the service, if you don't see either one, change all to 'restart the service' also make sure that the bottom 2 boxes are set to 1 & 1 each. Now click OK and then again click print spooler right click and restart the service, that should fix the problem. Let me know if it fixed the problem.
