Described is a method for optimizing ribbon usage by identifying areas that contain white space in text, graphics and image print tasks. (Image Omitted) Most APA print technologies that produce high quality print and use ribbons for printing have high supplies cost. One example is R2T2 (Resistive Ribbon Thermal Transfer) technology which produces very precise, dark print at high resolution by heating the print head and melting the ink to the paper. To make the printer cost effective to operate, special methods for manipulating the print head and ribbon intake mechanism must be used in the printer software to maximize the number of characters that will be printed from each ribbon.
