    Autocutter Module This printer is equipped with an autocutter module for cutting of the roll paper and a manual cutter for manual cutting. The autocutter has two opposing cutter blades that operate like a scissors to cut the paper. It is a separate cutter blade-type mechanism that does not require passage of the roll paper through an autocutter mechanism slit.
  • Page 24 TM200 Control Circuit Thermal head driver circuit The print head of the receipt printer mechanism is a thermal type print head with 576 dots per line. All print head control is performed via a gate array. A driver is built into the print head, and sending of print signal DATA-IN, which is synchronized with the CLOCK signal, to the driver sets the print/non-print status of each dot.
