A printer in one example includes a thermal printhead with resistive heating elements. A motor is provided in the printer for conveying paper to the thermal printhead. A power supply is provided to supply power to the thermal printhead and the motor. A processor is configured to cause the supply of power to the motor to be paused after the supply of power to the thermal printhead exceeds a power threshold value and then to resume the supply of power to the motor after a predetermined period of time elapses after the pause of the supply of power to the motor.

A dryer management system includes a global dryer control system and a closed loop dynamic dryer control system to manage drying of a material deposited on web. The global dryer control system analyzes information regarding a production run to determine a web conveyance speed and a maximum web temperature. The closed loop dynamic dryer control system monitors an indication of a temperature of the web to maintain the indication of the temperature below the maximum web temperature. The closed loop dynamic dryer control system also analyzes images of the web to determine if the material is being insufficiently dried.

Control of the print temperature for a thermal printer is disclosed. Two temperature sensors are used to sense the temperature of both the thermal printhead and the environment around the print medium. In this way, the energy applied to the thermal printhead's heating elements may be adjusted to match an ideal print temperature, which depends on both the printhead temperature and the print-medium temperature.

A thermal print head includes: a head substrate on which a plurality of heating resistance units are formed; a heat sink thermally connected to the head substrate, a recess being formed in a back surface of the heat sink which faces a surface to which the head substrate is connected; a metal member arranged in the recess; and an adhesive arranged between a bottom surface of the recess and the metal member. The recess viewed from a direction perpendicular to the back surface includes: an area where the metal member is arranged, and a groove area where the metal member is not arranged. A portion of the adhesive is arranged in the groove area.

The disclosure discloses a printer comprising a first control portion configured to control a feeder and a conducting device to perform printing on a recording medium. The first control portion executing a first processing, a second processing, and a third processing. In the first processing, printing on the recording medium is performed while feeding the recording medium to a forward direction, based on first print data. In the second processing, printing on a first predetermined section is performed while continuously feeding the recording medium to the forward direction, based on second print data, triggered by receipt of a print stop instruction in the middle of the first processing. In the third processing, feeding the recording medium to a reverse direction is performed and, with current conduction to the heating elements stopped, making the heating elements face the first predetermined section for a first predetermined amount of time.
