PRINTR:- A Text and Graph Plotting System with Expanded Capabilities

Abstract

A system for using control character sequences to extend a printer's character set and to more efficiently handle graph data and drawings has been written as a machine language program for the PDP8 computer with electrostatic plotter. Features added to text files include Greek and mathematical symbols, superscripts, two levels of subscripts and overstruck (superimposed) bars, dots and combined bars and dots. Plot files have two modes using 8 or 12 bit data words and may be either continuous scan or byte addressed. Plot and Text files may be mixed but not superimposed. (Author)
