According to an embodiment, there is provided a printer including a plurality of printing modes. A first printing mode is a printing mode for discharging a label by a transfer device, the label being still attached to a backing sheet. A second printing mode is a printing mode for discharging the label by the transfer device while peeling off the label from the backing sheet. The printer controls power supply from a storage battery such that a printing device performs printing at a first printing speed when the printing mode is the first printing mode and such that the printing device performs the printing at a second printing speed when the printing mode is the second printing mode, the second printing speed being slower than the first printing speed.
