Have a wireless hookup between an HP Pavilion and an MX882.  Been working great past year.....then one day, my printer would not respond.  My scan function works from the computer so Iknow that my wireless is working.  I can make copies so I know that my printer is working.  I spent 3.5 hours on line with a tech who  including gave up.  He did everything imaginable reinstalling the soft ware. Nothing! I still get the error message "Printer not responding." Can anyone help me resolve this problem?  Thank you.
