Hi
Welcome to Microsoft Answers!
I would suggest you to run Fix it, that automatically diagnoses and repairs problems with printing, installing a printer, connecting to a network printer, and other related errors. To do so, click this link and follow the instructions:
http://windows.microsoft.com/en-US/windows-vista/Troubleshoot-printer-problems
A print spooler is software that temporarily stores print jobs on the computer hard disk or in memory until the printer is ready to print them. If you've been waiting an unusually long time for a document to print, or if you see an error message
about the print spooler, spooler subsystem, or spooler resources, you might need to change and then restart the Print Spooler service on your computer.
To do this, we recommend that you save your work, and then restart the computer to restart the Print Spooler service. If you don't want to restart the computer, try these steps instead.
To change or restart the Print Spooler service
You must be logged on as an administrator to perform these steps.
1. Click start, type services.msc, right click on services.msc and then
click “Run as an Administrator”
2. Right-click thePrint Spooler service, and then click
Properties.
3. On theGeneral tab, next to
Startup type, make sure thatAutomatic is selected.
4. If the service is not already running, underService status, click
Start, and then click OK. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
Good Luck
