Champagne and perfume are expensive. However, a consumer group found that printer ink is one of the world's costliest liquids. The consumer group "Which?" said printer ink from technology companies is pricier than a lot of champagne. It can be up to 286% more expensive than ink from companies that do not make printers. The group said that some branded printer ink can cost $846 a litre. An expert said printer ink shouldn't cost more than perfume.
Non-branded ink can be as good as, if not better than ink from printer makers. The expert said lots of non-branded ink is better and cheaper than branded ink. "Which?" said non-branded ink could save people $398 a year. It said deciding which ink to use should be "a personal choice". The printer maker Epson said: "As non-genuine inks are not designed or tested by Epson, we cannot guarantee these inks will not damage the printer."
