The Flexowriter could be attached to Friden calculators and driven by paper tape to produce bills and other form letters which had names of customers and amounts of bills filled in automatically. This gave them the Flexowriter teleprinter, an electric typewriter capable of being used as part of unit record equipment developed in World War II for the Department of the Navy to automatically type "regret to inform you" letters to the survivors of fallen servicemen, the predecessor to modern computers. In 1957, Friden purchased the Commercial Controls Corporation of Rochester, New York.
