One of the drawbacks of thermal printing, be it resistive or conventional, is the large use and cost of supplies (ribbons). This problem is particularly acute in the case of resistive ribbon thermal transfer that employs very expensive ribbons. To alleviate this problem, one prior method for reusable R2T2 has been developed. The printing technique makes use of polyimide-graphite ribbons as reusable medium for the resistive part of the ribbon. This ribbon can be reused at least 600 times and thus is employed as a belt. The belt is inked and reinked by several methods, such as transfer of ink from a regular thermal printing ribbon. After the printing process, the residual ink has to be cleaned off. Most of the problems of this technology are associated with incomplete cleaning of the residues.
