2 identical HP printers both having smudgy ink at the same time - changed cartridge, changed paper still no good. Bought an Black XL cartridge from Tesco Plc £17 again same problem - phoned HP the person I spoke with said Tesco cartridge a counterfeit - I said what the UK's largest retailer have counterfeit cartridges told Yes. Told to buy HP product £53.99 from Currys - for 430 pages - Feel that HP are deliberating stopping your printer using anything but their cartridges - which cost more than the printer. Will never buy an HP printer again.
