Abstract: A printer performs printing on a thermosensitive medium including a plurality of color developing layers including a first layer developing a first color and a second layer developing a second color. The printer includes a head and a control device performing a printing control including outputting a signal pattern based on post-conversion image data converted from pre-conversion image data to cause a plurality of heat generation elements of the head to selectively generate heat while controlling conveyance of the thermosensitive medium. In the converting, when target dots containing the second color is included in the plurality of dots in the pre-conversion image data, the control device converts a color of conversion dots to a conversion color containing the color developed by any one of the plurality of color developing layers.

Abstract: 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.

Abstract: A recording apparatus includes a recording head including a plurality of heating elements, a sheet-like recording medium formed of a plurality of laminated color-developing layers for developing a plurality of colors. A first condition is satisfied when a subsequent pixel, located at the same position as a target pixel to be recorded following the target pixel, is a pixel for developing a color of a bottom color-developing layer of the recording medium. In a case where a value of the target pixel in the image data is a predetermined value and does not satisfy the first condition, the pulse control unit controls the pulse so that a thermal energy to be applied to the recording medium by the recording head in forming the target pixel is lower than if the first condition is satisfied.
