Abstract:
1. A printer comprising: a recognizing unit adapted to recognize that USB interface cable has been connected and that a host is active; a discriminating unit adapted to discriminate whether printing is being executed through another interface other than a USB interface, upon recognition by said recognizing unit that the USB interface cable has been connected and that the host is active; and a processing unit adapted to, if it is determined by said discriminating unit that the printing is being executed through the other interface, start a USB enumeration when the printing through the other interface is finished, and, if it is determined by said discriminating unit that the printing is not being executed through the other interface, start the USB enumeration, wherein if it is determined by said discriminating unit that the printing is being executed through the other interface, said processing unit does not turn on a high side switch and turns on the high side switch and starts the USB enumeration when the print through the other interface is finished, and if it is determined by said discriminating unit that the printing is not being executed through the other interface, said processing unit turns on the high side switch and starts the USB enumeration.
