Function
Inquire power-cycle status
ASCII
[ENQ] <11>
Hexadecimal
05H 0BH
Decimal
<5> <11>
Function
Has the printer been power cycled since the last request?
Serial/Parallel, IEEE 1284
Parallel, non-IEEE 1284
Response
ACK <11> (06H 0BH)
PE low
Printer power has been cycled
since the last [ENQ] <11>.
NAK <5> (15H 0BH)
PE high
Printer has not power cycled
since the last [ENQ] <11>.
Description
The first time after a reset, the command will return [ACK] <11>, after
that the command will return [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 will both cause the printer to return power-up status.
Function
MICR read cancel
ASCII
[ENQ] <12>
Hexadecimal
05H 0CH
Decimal
<5> <12>
IPCL
none
Description
The [ENQ] command is a real-time command that forces a MICR read
command to stop and return no data. The command can be used to get the
printer out of a read command. It has no other effect on the printer and is
always acknowledged. (See another inquire command for a description). If the
read is complete before the ENQ <12> is issued, the read command will operate
normally.
