Hi @40-love,
Welcome to The HP Support Community.

I understand you are facing a printing issue with your HP Officejet Pro 8600 E-All-In-One Printer - N911a. Not to worry I will help you to get a resolution to resolve the issue.
Check Ink Levels and Cartridges
Check Ink Levels:
- Ensure that all ink cartridges have sufficient ink. Low ink levels can cause printing issues.
Re-seat Cartridges:
- Turn on the printer and open the ink cartridge access door.
- Remove the cartridges and reinsert them, making sure they are properly seated.
Replace Cartridges:
- If any of the cartridges are low or empty, replace them with new ones.
Printhead Cleaning
Manual Cleaning:
- Turn off the printer and unplug it.
- Open the ink cartridge access door and remove the printhead.
- Use a lint-free cloth lightly dampened with distilled water to clean the printhead and the contacts.
Automatic Cleaning:
- Use the printer’s built-in printhead cleaning function, which can be accessed through the printer’s control panel or the HP Smart app.

Firmware Update:
- Ensure your printer firmware is up to date. You can update the firmware via the HP Smart app or by downloading it from the HP Support website.

Network Connection

Print from Another Device
