Abstract
A printing system, a thermal printer, a printer driver, a printing control method, and a data storage medium control the printing process according to the type of thermal paper that is loaded into the printer when the paper is replaced. By appropriately controlling address selector , a print head controller stores black print pixel data and red print pixel data in first data buffer for storing low energy level print pixel data or second data buffer for storing high energy level print pixel data according to the type of thermal paper in use. A logic circuit unit outputs the current pattern data to the print head based on the low level print pixel data and high level print pixel data.
