Electronic printhead
This two-inch-long electronic printhead was a key element in the IBM-developed "resistive-ribbon" printing technology that "melts" characters onto the page. Printing became practically noiseless when compared with impact printing, which uses hammers or other electromechanical means. The technology was used in the IBM Quietwriter printers and typewriters. It could produce "letter-quality" printing at speeds up to 60 characters a second. (VV3171)
