5) Reverse Mode (Nibble/Byte) mode allows status to be transmitted from the printer.
(Using GS a, DLE EOT n, GS r, of GS I command)
・The transmitting buffer of the printer is 99 bytes. The host must transfer to Reverse
Mode to prevent loss of status. Being in the Reverse Idle state is desired when using
ASB. If this is not possible, always monitor the presence or absence of the transmitting
data from the printer. The ASB not transmitted but accumulated is transmitted
together (OR) with the latest status.
・Identification of information on each status is available.
