One of the person at work have a HP 6300 all in one printer (I hate those all in one). I reinstall the driver, it prints find except the print error message keep poping up. It tell me “there is an error while printing please click here for assistance” on the bottom right of the screen…..while the page is being printed!! how do I clear the error from keep poping up.

btw…its hook up through USB only..not networked.

Thanks
