HP88 Printhead gone faulty

Bought an HP88 printhead from First Shop which has gone faulty. First Technology tell me to take it to HP because they do not honour warranty.<br> <br> Contact Insure IT who inform me to take the printer in for repairs. I am liable for the cost of repair.<br> <br> I then contact HP who tell me to go to the supplier because they are not responsible.<br> <br> The cartridge has \Warranty Ends 2016/08/19"printed on it"""
