This command allows the printer to inform the host when the data in
the buffer has been processed, when the IEEE 1284 interface is in
unidirectional mode. When this command is sent to the printer, the
printer goes "Busy" until all data which has been sent to the printer has
been processed. The PAPER EXHAUST line shows the status for the
cash drawer or receipt paper as shown in the table.
Status information is limited to what can be sent by the dedicated lines:
BUSY, ACK, PAPER EXHAUST, and FAULT.
