What type of printer is the STP-131?
STP-131 is a thermal receipt printer. Thermal printer does not require inks, instead it applies heat to a special type of paper to change its color. Therefore, you should use thermal paper treated with special chemicals. (Only one side can be printed on.) STP-131 is an early model released by BIXOLON, and it supports only Serial and Parallel interfaces, and the printing speed is relatively slow. If you want a model with a faster printing speed, search the new products in BIXOLON homepage, www.bixolon.co.kr.
