A print system includes a head, a conveyance motor, a first connector, and a second connector, a power supply circuit. When a first power source is connected to the first connector and a second power source is connected to the second connector, the power supply circuit supplies at least some of a first power to the head and supplies at least some of a second power to the conveyance motor. The first power is a power of the first power source. The second power is a power of the second power source.

Print system

A printer includes a printing unit powered from a battery which is charged by a charge IC, and a processor. The processor sets a mode of the printer to a print mode, and sets the mode to a low-power mode in which total power consumption of the printer is lower than that in the print mode, in a state that the printing unit stops printing. In a case where the processor sets the mode to the low-power mode, the processor sets the mode to a first low-power mode, in which the charge IC is driven at a first SW frequency, when the charge IC works to charge the battery, and sets the mode to a second low-power mode, in which the charge IC is driven at a second SW frequency lower than the first SW frequency, when the charge IC stops the charge of the battery.

Printer with low-power mode

The disclosure discloses a printer. The printer comprises a feeder, a driving device, a printing head, a power feed device configured to supply electric power, a battery accommodating part configured to selectively accommodate either one of a primary battery and a secondary battery, a voltage detecting device, an exhaustion determining part configured to determine whether or not a print load voltage has reached a threshold value for exhaustion determination, a notification part configured to perform predetermined notification processing, a first setting part configured to set the threshold value to a first threshold value, a second setting part configured to store a threshold value for constant load voltage determination, a constant load voltage determining part configured to determine whether or not the constant load voltage has reached the threshold value, and a threshold value changing part configured to change the first threshold value to a second threshold value.
