What is the difference between thermal printing and impact printing?
Thermal printing cash registers have a printer head which gets warm to make the character impression on the paper. The thermal paper is like the paper used in a fax machine. Its contains heat activated toner which turns black when warmed. Impact printing cash registers use the transfer of ink from an ink roller or ribbon cartridge to make the character impression on the paper. They use plain or “bond” paper, called so as it is designed to allow ink to bond to it well.
