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.
