How can I explain this case citing utilitarianism, individual rights and distributive justice?

Case Three

Computer printer manufacturers usually sell printers at a low margin over cost and

generate much more income from subsequent sales of the high-margin ink cartridges required for

each printer. One global printer manufacturer now designs its printers so that they work only with

ink cartridges sold in the same region. Ink cartridges purchased in the United States will not work

with the same printer model sold in Europe, for example. This "region coding" of ink cartridges does

not improve performance. Rather, it prevents consumers and grey marketers from buying the

product at a lower price in another region. The company says this policy allows it to maintain stable

prices within a region rather than continually changing prices due to currency fluctuations
