摘要： A thermal head drive unit comprises electric power supply means for supplying electric power to heat-generating resistor elements arranged in a line in a thermal head. Head drive means is provided for electrically driving the heat-generating resistor elements in a lump by supplying electric power continuously variably in time to the heat-generating resistor elements depending on input gradation data. Head drive control means controls the head drive means in such a manner that, in a one-line recording time period composed of a power supply time during which electric power is supplied to the heat-generating resistor elements and an intermission time during which no electric power is supplied to the heat-generating resistor elements in disregard of the gradation data, the intermission time occupies a part not more than approximately 40% in the one-line recording time period.

摘要： A method, apparatus, and computer program product are described herein for controlling a printing device. In an example embodiment, a print line is divided into frames and frame dot states are determined based on neighboring frame dot states. Maximum motor speeds of the printing device may be adjusted so that actual motor speeds change gradually during printing. The print engine may detect a printhead type by sending a signal to the printhead and receiving a response. Motor torque is dynamically controlled based on type of media and/or labels present on the media.
