摘要： A printing device includes: a printing unit printing on a recording paper; a feeder unit having a roller that rotates about a shaft and feeds the recording paper and a motor that rotates the shaft; a detection unit detecting the rotation of the shaft; and a control unit controlling the printing unit. The control unit calculates an electrifying time during which the printing unit is electrified and a non-electrifying time during which the printing unit is not electrified following the electrifying time, based on a detection signal from the detection unit. When the calculated non-electrifying time is less than a predetermined time, the control unit corrects the non-electrifying time in such a way that the non-electrifying time becomes equal to or longer than the predetermined time, and causes the printing unit to print.

摘要： A printing device includes: a printing unit printing on a recording paper; a feeder unit that has a roller rotating in a first direction about a shaft and feeding the recording paper, and a motor rotating the shaft; a detection unit detecting a rotation of the shaft in the first direction and a rotation thereof in a second direction opposite to the first direction; and a control unit controlling the feeder unit, based on the rotation of the shaft detected by the detection unit. The control unit causes the motor of the feeder unit to rotate the shaft in the first direction and then stop the shaft, and subsequently causes the motor to rotate the shaft in the first direction before the printing unit prints, based on the rotation of the shaft in the second direction detected by the detection unit.

摘要： The temperature of heat elements of a thermal head can be controlled with high precision by a process with a low processor load. A printer 100 that prints on thermal roll paper 102 based on print data has a thermal head 134 with multiple heat elements 136 arrayed in a sub-scanning direction CR perpendicular to the conveyance direction F of the thermal roll paper 102. The printer 100 has a current control unit 112 that segments the heat elements of the thermal head 134 into plural blocks, and controls the energize timing of the heat elements in each block based on the number of heat elements 136 that are energized in the thermal head 134.
