Enquire (ENQ)
Upon receipt of an ENQ command, the printer responds with 25 bytes of status
information bounded by an STX/ETX pair. The Bi-Com protocol works only in the
Multi Job Buffer mode. The status information is defined as follows:
<STX>{ 2 Byte ID}{1 Status Byte}{6 Byte Label Remaining}{16 Byte Job Name}<ETX>
ID - This is a two byte number identifying the current print job ID. The print
job ID is defined using the <ESC>ID Job ID command transmitted with the
print job (see Job ID Store in the command listing for more information on
how to use this command). The range is from 00 to 99.
Status - A single byte defining the current status of the printer (see the Status
Byte Definition table).
Label Remaining - Six bytes defining the number of labels remaining in the
current print job. The range is from 000000 to 999999 labels.
Job Name - 16 bytes of ASCII characters identifying the name assigned to
the job by the <ESC>WK Job Name command. If the Job Name is less than
16 characters, the field will be padded with leading zeroes.
If an ENQ is received after the print job specified in the ID bytes has been completed,
or there is no data in the buffer, the printer will respond with two “space” characters
(20 hexadecimal) for the ID number, six “zero” characters (30 hexadecimal) in the
Remaining Labels bytes and the 16 byte Job Name.
Cancel (CAN)
If a CAN (18 hexadecimal) command is received , it will stop the print job and clear
all data from the receive and print buffers. A delay of five milliseconds or more is
required before any new data can be downloaded. The CAN command is effective
immediately upon receipt, even if the printer is off-line or in an error condition. The
printer will return an ACK (06 hexadecimal) if there is no printer error condition and
a NAK (15 hexadecimal) if an error condition exists.
Print Job
Upon receipt of a valid print job (<ESC>A...<ESC>Z),anACK (06
hexadecimal) will be returned by the printer if there are no errors and a NAK (16
hexadecimal) if a printer error exists.
Print Stop (DLE)
If a DLE (10 hexadecimal) is received by the printer, the print process is stopped and
an ACK (06 hexadecimal) is returned if there are no errors and a NAK (16
hexadecimal) if a printer error exists.
Print Start (DC1)
If the printer has been stopped by receipt of a DLE (10 hexadecimal) command, it
can be restarted by sending a DC1 (hexadecimal 11) command. Upon receipt of this
