This is an extremley flawed service. Please be very very careful not to remove the printer from your HP Inatant Ink account. Or it will no longer be eligable for enrollment. They do not make this clear at any time during the point of sale of the HP printer or at the point of sale of the HP instrant ink program. My daught happened to 'Un-enroll' the printer on onlt three occasions. Now she is left with a printer that will cost the earth to run. Or HP reccomended buying a new printer! I dont think so. Please be careful and think twice. Or you will be left with a £200 printer paper weight.
