TL;DR: Signature image information is converted from scanner input data into lines of character spaces which can conveniently be presented on a matrix printer in this paper, both the method of image conversion from input scans to output lines of characters and apparatus for interpreting control information accompanying character picture element information are disclosed.
Abstract: Signature image information is converted from scanner input data into lines of character spaces which can conveniently be presented on a matrix printer. Both the method of image conversion from input scans to output lines of characters and apparatus for interpreting control information accompanying character picture element information are disclosed. An efficient format for presenting the control information and reducing the amount of picture element data stored and handled is also disclosed.
