Hi@KathrynDay,

Welcome to the HP Support Community! I'd like to help!

I see you are experiencing printing issues with the HP Printer not printing Black. I apologize for the Inconvenience. 

I have a few recommendations 

• To resolve this issue, use only genuine HP cartridges. Additionally, you can remove the black cartridge to print only with the tri-color cartridge, replace any empty or defective cartridges, or clean the printhead.
• Check if the vents of the cartridges are clogged. You can fix this by gently using a pin to clean up the clog on the vent.
• Try using a different ink cartridge to determine if your printer is able to recognize cartridges.
• Click this link if The printer is working, but the printed output is missing black https://support.hp.com/us-en/product/hp-deskjet-2510-all-in-one-printer-series/5157438/document/c043...
