What is printer error 79 on the HP Laserjet?
If you encounter the printer error 79: Service Error, you should shut off the HP printer, wait for about 5 seconds, and turn it back on. The switch is located in the bottom right corner of the front panel. After the printer warms back up, it should be printing okay again. If not, you may want to think about removing your print job from the queue. In general, shutting the printer off and turning it back on resolves a lot of errors. But if you’ve done it once, and the printer still hangs up, please contact the repairs officer.
