It is difficult, if not impossible, to present mathematical expressions in the text of an engineering paper when a home computer/word processor/printer system is used to prepare the manuscript. This thesis approaches the problem from the standpoint of inserting hardware between any small computer system capable of generating ASCII characters serially and a given printer capable of dot matrix graphics. This hardware is a microprocessor programmed to have the intelligence to decode ASCII character strings from the host computer and cause the printer to print the mathematical symbols and equations represented by the ASCII character strings. Basic concepts of mathematics printing and an introduction to the hardware used in this interface are presented in chapter two. Chapter three brings together these concepts in detailing the hardware, software, and character/equation design and development of the printer interface. Some interesting problems and limitations of the mathematical expression printer interface are discussed in chapter four, along with the conclusions of this study.
