I have an HP Officejet Pro L7780, but my ink catridge is past due and has ink.  How can I trick the printer to print.

Thank you for joining the HP Community

I suggest you do a Hard Reset on the printer

(1) Turn the printer on, if it is not already on.

(2) Wait until the printer is idle and silent before you continue.

(3) With the printer turned on, disconnect the power cord from the rear of the printer.

(4) Unplug the power cord from the wall outlet.

(5) Wait at least 60 seconds.

(6) Plug the power cord back into the wall outlet.

NOTE: HP recommends connecting the printer power cord directly to the wall outlet.

(7) Reconnect the power cord to the rear of the printer.

(8) Turn on the printer, if it does not automatically turn on.

The printer might go through a warm-up period. The printer lights might flash, and the carriage might move.

Wait until the warm-up period finishes and your printer is idle and silent before you proceed.

Use an automated tool to clean the printhead

5. Wait while the printer cleans the printhead.

6. A test page prints after the printhead is cleaned.

If the issue persists, replace the Ink Cartridge.
