I had printer problems with ccleaner. I added win 7 paranoid list in the included files. I think there is something in that list that is del. the folder printers in my folder (C:\Windows\System32\spool\) folder. What i did is added this to my exclude list in ccleaner C:\Windows\System32\spool\ That way it doesn't del. the folder printers in the spool folder. I would have to restart the spooler every time I neede to print something, if I ran ccleaner.
This worked for me!
