Abstract
This paper describes a new teleprinter that can print graphs as well as characters through the combination of an 
plotter using a high-speed incremental servo with a large-scale integration (LSI) character pattern memory that converts telegraphic signals into plotter signals. This device prints 20 characters per second, and the characters are formed by connecting segment vectors in eight different directions with one stroke. Design criteria of the incremental drive system and the selection of the symbol font are also described.
