Abstract: A thermal printer control device for controlling a thermal printer which includes a thermal head and which is configured to perform printing on a sheet having a mark arranged thereon. The thermal printer control device includes: a sensor value acquisition module configured to acquire a sensor value detected by a sensor configured to detect an intensity of reflected light obtained when light is irradiated on the sheet; a threshold value calculation module configured to calculate a threshold value for detecting a presence or absence of the mark based on the sensor value acquired by the sensor value acquisition module; and a determination module configured to determine the presence or absence of the mark based on a result of comparing the sensor value acquired by the sensor value acquisition module and the threshold value calculated by the threshold value calculation module. The threshold value calculation module is configured to calculate the threshold value based on a first sensor value which is the sensor value obtained when the mark is detected and a second sensor value which is the sensor value obtained when the mark is not detected.

Abstract: A portable terminal has a thermal head. The portable terminal includes a first sensor unit configured to detect presence or absence of a sheet, a second sensor unit configured to detect information related to a mark provided on the sheet, and a sheet determination unit configured to determine a kind of the sheet. The sheet determination unit is configured to determine a kind of the sheet based on a result of detecting information related to the mark with use of the second sensor unit after the sheet is conveyed in a reverse direction with respect to a direction of discharging the sheet.

Abstract: A printer includes: a first connector to be used to input electric power supplied from an outside; a second connector to which a communication terminal is to be connected, and which is to be used to output at least a part of the electric power to the connected communication terminal; a printing control unit configured to control operation of a printing unit configured to perform printing on recording paper; and an adjustment unit configured to adjust a maximum amount of the electric power to be output from the second connector, of the electric power supplied from the outside, to a first amount of power when the printing unit is not under a printing operation, and adjust the maximum amount of the electric power to be output from the second connector to a second amount of power when the printing unit is under the printing operation, the second amount of power being smaller than the first amount of power.
