Abstract
A thermal head controller includes a central processing unit (CPU), a storage unit, an arithmetic unit, a controller, and a thermal head. The CPU reads print data stored in the storage unit. The storage unit holds print data to be printed on a stamp print face, which are transferred from a host computer. The CPU transfers the read data to the arithmetic unit, and causes the arithmetic unit to perform print-pattern processing. The arithmetic unit stores pattern data in its shift register before processing the stored pattern data. The print-pattern processing is performed so as to prevent fine print from being erased due to the deformation of the stamp print face caused by heat conduction in polyethylene foam sheet when the stamp print face is formed. The CPU uses the controller to control the thermal energy of dots positioned on the border between print dots and non-print dots on the thermal head.
