I have an HP C4280 Multifunction. Cartridge properly functioning only after 300 impressions (for theoretical amount of 1000), the printer no longer recognizes the cartridge and displays an error message "damaged cartridge or absent!" Forced to change it, you must first make non XL cartridges to enjoy every last drop from the cartridge. HP is aware of the problem but does nothing to remedy this defect. I do not advise HP printers !! Amazon thank you for the lowest market price though!
