Hi, I have a Deskjet 2050 Special Edition all in one printer.  The product number is CH355B.  It was purchased 2010 in the UK but I live in Greece.  I recently visited Thailand and bought new printer cartridges HP61XL (black and tri-colour) for my printer but when I returned home the cartridges are not recognised by my printer.  But on the cartridge box its says HP Deskjet 2050 and that’s why I bought them.  Normally I use 301XL but I wasn’t worried because it said on the 61XL  box about 2050.  So is there anything I can do?  I don’t have another 50 euros for more cartridges
