I nk cartridges are the headline running cost of any printer but you need to add in the price of high-quality paper as well for photo prints. Some inkjets come with options for standard, XL and XXL cartridges.

Canon MegaTank and Epson EcoTank printers have larger ink tanks, replenished from bottles. This can work out much cheaper for ink but there’s a bigger up-front cost. Here’s how the cost of ink works out, using the highest-capacity options where available.
