NAK <5> (15H 0BH)
Printer has not power cycled since the last [ENQ] <11>
Description
The first time after a reset, the command returns [ACK] <11>, after that
the command returns [NAK] <11>. The command allows the application
to determine if the printer has been power cycled and needs to be
reinitialized. The [ENQ] <10> command and the INIT signal on the
parallel port both cause the printer to return power up status.
