Rhinotek’s chairman has sharply criticized Hewlett-Packard over a lawsuit asserting that the inkjet cartridge refiller falsely advertises its products as new. “I think HP is utilizing a bullying tactic,” Gerald Chamales, who also is founder of the 150-employee company in Carson, Calif., said late Tuesday. “I think consumers are tired of being gouged by what I call the cartel, which is the major printer manufacturers, led by HP, Lexmark and Canon, (and which is) forcing people to not have a choice when it comes to ink and toner cartridges.”
