Product: HP Officejet Pro 8620
Operating System: Mac OS X 10.9 Mavericks

My printer has been printing pages by itself with emoji like characters (heart, slash, Asterick) followed by the text "Cookie: mstshash=Administr" followed by another weird character. Has happened several times in the past week. Why is this happening and how can I stop it?

 

Thanks,

Joanne
