I have had my printer(HP Deskjet 9800) for a number of years and never had any trouble until now. When i go to print anything it always prints a page with numbers on it (sometimes just a 2 other times 2345X)in the upper left hand before it prints the job. I have tried to turn it on and off and unplug it but nothing seems to help, hope someone can help, I'm wasting a lot of paper
