US woman sues over ink cartridges

...The cost of printer cartridges has been a contentious issue in Europe for the last 18 months.

The price of inkjet printers has come down to as little as £34 but it could cost up to £1,700 in running costs over an 18-month period due to cartridge, a study by Computeractive Magazine revealed last year.

The inkjet printer market has been the subject of an investigation by the UK's Office of Fair Trading (OFT), which concluded in a 2002 report that retailers and manufacturers needed to make pricing more transparent for consumers.
