Fourth byte (paper sensor information)
■
With a serial interface, the printer transmits a 4-byte ASB status message without confirming whether the
host can receive data. ASB status, except for the XOFF code, is always consecutive.
■
With a parallel interface, when ASB status is used, it is desirable for the host to be in a reverse idle state.
However, if the host computer cannot always be in the reverse idle state, it is necessary to enter Reverse
Mode regularly to watch for ASB status. If the host is not in the Reverse Mode for a long time, and the
printer has to store ASB status changes to be transmitted, the following 2 sets (8 bytes) of ASB status are
changed to special data and transmitted prior to other transmission data when the host enters Reverse
Mode:
•
ASB-1: Status information that shows whether status changes occurred
•
ASB-2: The latest ASB status information
