This line printer was developed in 1966, when data transfer service started, as a terminal device with 1200 - 2400bps data transfer capability.
The print method was the Type Belt Method which was a unique and major technology by OKI, drawing on its achievements in output devices of computers. This printer had a hundred and twenty eight types in ISO code. It printed a hundred and fifty lines per minute and each one line had a hundred and thirty two characters. A size of the mechanism area was reduced to the utmost limit. Instead of an expensive core memory, a magnetostrictive delay line for the memory unit was used for the control area. In addition, a single motor which drove the belt, fed paper and drove ink ribbon, brought cost reductions in the drive line. This product was introduced as a line printer, achieving epoch-making low costs, small size and user-friendliness. It made characters visible immediately after they were printed out and enabled printed sheet to be cut off after a few lines. Communication with a host computer through a modem enabled the device to detect and correct an error by vertical parity check of received codes and horizontal parity check of a block of codes.
This printer was one of OKI’sour best-selling products used by a large number of computer manufacturers as the terminal for data transfer device, as well as output device for the financial market and minicomputers.
