hese are some things you can do that may fix your problem:
1.Check the cables first. Unplug and Re-plug the printer into the computer. Be sure the power cable is plugged in and the outlet works.
2.Check to make sure the correct printer is selected in the Print Dialog box. If you are on a network, you could be sending the output to a printer in someone else's room.
3.Can you print from a different application? Does it only occur with a certain application or is it not working with anything?
4.Can you print a test page directly from the printer with it unconnected to the computer? Each manufacturer has their own special series of buttons to hold down for this self-test. Most of the time it will be in the user's manual.
