Hello Tamkey-birddog,
Welcome to the HP Forums!
I understand your Officejet 6500A is printing "Gibberish". How is this printer connected? Wireless or USB? What is your operating system on your computer? Windows.
If your printer is connected by a USB cord, then please follow this HP document on Continuous Pages of Strange or Garbled Characters Print in Windows.
Please post your results, as I will be looking forward to hearing from you. :smileyhappy:
