So, apart from HP with their expensive print head with ink changing system, the only printer which has a partial endorsement is the Canon Pixma iP4700. It appears that a large ink reservoir system for this printer can be procured which helps to overcome the ridiculous ink costs, but it is not squeaky clean according to some of the reviews. At least this ink reservoir with plenty of ink to last for a while is a little less expensive than the printer itself!
Any other ideas?
P.P.
