Hardware Description

Earl Masterson and J. Presper Eckert developed the UNIPRINTER, the first commercially available high speed printer. The UNIPRINTER was a line printer, capable of printing 120 characters simultaneously. The UNIPRINTERs were sold as an optional printer with the UNIVAC I. It was based on a rotating drum containing a series of complete characters. It could print at 600 lines per minute, which was four times faster than its closest competitor's printer, IBM's tabulators.
