FACOM 642 Line Printer

This was a line printer from Fuji Tsushinki Manufacturing Co. (currently Fujitsu Ltd.) which realized high-speed printing by using a type drum based on a new manufacturing system, and a flag bit control system for improving effective printing speed. The company had consistently developed line printers using the type drum system, and that technology came to fruition with the FACOM 642 printer which was completed in March 1966. In terms of performance, reliability and other points, this printer achieved the highest level for a mechanical printer at the time.
