The shipping was very fast, the ink cartridges were beautifully packaged. The use of cartridges was 4280 printer from the HP Photosmart C. Every now and then there was a communication error between the printer and the cartridges but after resetting the printer, the problem was solved. It is well known that the HP printers have any memory functions and do not always recognize the cartridge / want. The quality of ink is good, the cartridges fulfill their purpose. Many Thanks!
