Abstract
An image forming apparatus includes a Universal Serial Bus (USB) interface and a controller. The USB interface includes a control endpoint for control transfer and a data endpoint for data transfer. The controller is configured to transmit, in response to receiving a status request command from a USB-connected terminal device through the control endpoint, status information of the image forming apparatus to the USB-connected terminal device through the control endpoint. The USB-connected terminal device is a terminal device connected to the image forming apparatus through a USB connection.
