Can a hp 88xl cyan office jet 7780 cartridge with exp date of March 2009 work in September of 2009?
This page indicates that the Officejet 7700 series ink expiration has an override so you can continue to use expired cartridges.

A solution for some HP printers.
I bought an HP 1100d Business Inkjet a month ago. Although this printer model is 7-8 years old, the one that I bought was still brand new in box. It had never been used! Needless to say the cartridges that came with it had an expiry date of 2006, so the printer gave me an expired cartridges error as soon as I tried to print the first test page.
I found that if I set my computer's clock back to a year prior to the cartridge expiry date the printer would print. But MORE IMPORTANTLY I found that after setting the clock back a few years, and doing a couple of prints, if I then reset the clock back to the real year (2009), the printer would CONTINUE to be able to print with the expired cartridges!
I have tried this solution on three computers at home, one with a direct USB connection, and a couple printing through my network, with an HP print-server connected to the 1100d printer.
For all three computers, they woould not print until I reset their clock back to about 2005, but the all continued to be able to print after I reset their clocks forward to 2009. I did this procedure a few weeks ago, the computers have been turned off and on many times since then and the printer has been turned on and off a few times. It continues to be able to print and my computers are all set to the correct year (2009).
