Notes of receiving the status from the printer

For USB interface:

  • The status of the printer is sent to the host computer via the USB bulk transmission method.
  • The USB bulk transmission method is a host-controlled transmission method. Unlike RS-232 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. In order to avoid lack of status data, it is necessary to periodically retrieve status data at the host computer.
