Region encoding printer cartridges
Taking a cue from the practice of region encoding of DVDs, hardware manufacturers in US have started making their products only usable in the country of their production. H-P has quietly begun implementing “region coding” for its highly lucrative print cartridges for some of its newest printers sold in Europe. Try putting a printer cartridge bought in the U.S. into a new H-P printer configured to use cartridges purchased in Europe and it won’t work.
