Transmits current status of the cash drawers. One byte
is sent to the host computer. In DTR/DSR protocol,
the printer waits for DSR = SPACE. If a drawer is not
connected, the status will indicate it is closed.
Exceptions
Unlike the A756, that had a dedicated connector and
resultant dedicated status reporting for each cash drawer,
the A760 has a single connector that shares data reporting
from either cash drawer. When either cash drawer is open,
an open status is reported by the printer.

processed.. The PAPER EXHAUST line shows the status
for the cash drawer or receipt paper as shown in the table.

dedicated lines: BUSY, ACK, PAPER EXHAUST, and
