Query: Not for the L7680

I have an Officejet L7680 all-in-one printer. The proper ink for this printer is "Officejet 88." I have never had a problem buying ink for this device until a recent order.I purchased an HP 88 Black/Yellow Officejet Printhead in Retail Packaging. Right on the packaging, it states that the product is for the L7680. When I opened up the package, it was obvious that the product would not fit my printer. The only difference I can see is that in the past I have purchased "HP Ink Cartridge" in the 88 series. What I received is an "HP Printhead" in the 88 series. Why would HP use the same numbering series to describe two different products? And why would it be label to lead one to believe it can be used with the L7680?Amazon, as usual, refunded the money for the return.
