A method for managing printing of data by a thermal printer. The thermal printer includes a thermal print head. The thermal print head has a plurality of points, each point having an effective resistance r.sub.d, and is powered by a power source. The method includes the following actions: measuring a voltage U given by the power source of the thermal printer; measuring an internal resistance r.sub.u of the power source; and computing a duration t for heating a number n of points as a function of the voltage U of the power source, the internal resistance r.sub.u of the power source, at least one effective resistance r.sub.d of at least one point corresponding to a dot to be printed for the printing of the data and as a function of at least one value of parasitic resistance r.sub.p of at least one element of the thermal printer.

The disclosure discloses an electronic apparatus including a charging device, a plurality of operation mechanisms, and a CPU. The CPU is configured to execute an information acquisition process, a voltage decision process, and a charging control process. In the information acquisition process, capacity-related information corresponding to a charging capacity required for operation of the operating mechanisms is acquired. In the voltage decision process, a charge stop voltage is decided in accordance with the capacity-related information acquired. In the charging control process, the charging device is controlled to stop the charging process by using as a trigger an attainment of the charge stop voltage decided after start of the charging process.

Thermal printheads need a power and/or a data cable to deliver energy to the thermal printhead to print. With a wireless thermal printhead, however, a printer can run without using a power or a data cable. By removing the cable, benefits include shrinking the printer size, increasing durability of the printer and making it easier to change a thermal printhead.

The disclosure discloses a printer including a memory storing computer-executable instructions that cause the printer to further perform a first determination process and a second determination process. In the first determination process, it is determined whether or not a preceding line location reaches an inter-page position between two adjacent pages of a print-receiving medium. In the second determination process, it is determined whether or not the either one state of the first and second energization state is switched to another state of the first state and the second energization state. In the case that it is determined that the either one state is switched to said another state, the print parameters being calculated in the parameter calculation process.

According to one embodiment, there is provided a power reception device including: a power reception coil, a power reception unit, a notification unit, and a control unit. The power reception coil receives power from a power supply device in a non-contact manner. The power reception unit causes the received power as a charging current to flow to a load. The notification unit notifies that a relative position of the power reception device to the power supply device is inappropriate. The control unit starts charging by the charging current which is set to a first current value and controls the charging current so as to gradually increase the charging current. If the charging is stopped before the charging current reaches a second current value larger than the first current value, notification is performed that the relative position of the power reception device to the power supply device is inappropriate.
