A printer includes a battery, and a conveying unit powered by the battery and configured to convey printing media at a first speed and a second speed lower than the first speed, a printing unit that prints on the printing media conveyed by the conveying unit, a measuring device that measures a residual capacity of the battery, a display for displaying information related to the residual capacity of the battery, and a processor configured to control the display to, when the residual capacity of the battery is not less than a predetermined residual capacity value, display first information indicating a total number of the printing media that can be printed at the first speed, and when the residual capacity of the battery is less than the predetermined residual capacity value, display second information indicating a total number of the printing media that can be printed at the second speed.

Printer

According to an embodiment, a printer includes a battery, a display, a memory and a processor. The memory stores a predetermined residual capacity of the battery of the printer and amount information of a printing medium on which a predetermined printing data can be printed with the predetermined residual capacity in association with each other in advance. The processor controls the display such that the amount information corresponding to the predetermined residual capacity stored in the memory is displayed on the display, in a case where determining that the residual capacity of the battery is reduced to less than the predetermined residual capacity.
