2) Status transmission from printer with USB interface

With this interface, the status of the printer is transmitted to the host computer via the USB bulk transmission method.

The USB bulk transmission method is a host-controlled transmission method. Unlike RS232 transmission, it cannot spontaneously interrupt data transmission to the host computer.

The printer has a 128-byte status data buffer. Statuses that exceed the buffer capacity are cancelled. In order to ensure that there is no lack of status data, it is necessary to periodically retrieve status data at the host computer.
