Spooler service problem

Restart the spooler:

Open the "Start" menu and click the "Run" option. Type "services.msc" in the run field and press "Enter."

Scroll down the list in the main window until you find the "Print Spooler" service. The services are listed in alphabetical order.

Click on it to select it. Click the "Restart" link located to the right of the service list. Wait for the print spooler to stop and start again before attempting to delete a print job or start a new one.

Go to the printer's manufacturer site , select your model, download the driver and install.
