I have an HP Laserjet 2420d connected to my MAC PRO using MAC OS 10.5.6. All of a sudden I have started getting the following error message when I try to print something: 49 4C02 Service Error. What does that mean and how do I correct it. Thanks, Frank

Hi Frank,
If you google that error code, it will take you to a web sight called Fixya.com. There you will find your answer. It's basically a firmware error. It's recommended to download the lastest firmware and update your printer.
