Hello philgolf,
I would like to assist you with getting the printing function working on your HP Officejet Pro 8600 Plus e-All-in-One Printer - N911g. I recommend downloading and running the HP Print and Scan Doctor as it should resolve this printing issue for you. Also, make sure you check for Windows Updates that could be available. What kind of firewall/security do you have installed on your computer?
Looking forward to your response.
Thank you,
