Are you able to press a button on the printer to print a test page?
Did the printer stop printing or did you connect the printer and it would not print?
I would check the status of the Print Spooler Service.
Click on the Start button and select Control Panel, Administrative Tools, Services. Locate Print Spooler in the list. Check that it has started and that the StartUp type is Automatic.
I suspect that it has stopped and that just starting it will not solve the problem.
You may need to show hidden files. Type Folder Options in the search box above the Start button and select View, Advanced Settings and verify that the box before "Show hidden files and folders" is checked and "Hide protected operating system files" is unchecked. You need to scroll down to see the second item. You should also make certain that the box before "Hide extensions for known file types" is not checked.
Now access Windows Explorer and select c:\windows\system32\spool\printers. Normally this folder should be empty but there is a problem when files with “spl” and “shd” extensions stick there. Delete the files and restart your computer. This may resolve your immediate problem.
