Status transmission from printer with USB interface
In order to ensure that there is no lack of status data, it is necessary to periodically retrieve status
data at the host computer.
Unlike RS 232C 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
canceled.
